Graphing Ellipses & Circles

I introduce the 4 conic sections, explain the basic structure of Ellipses & Circles, and finish by working through three graphing examples after putting these equations in standard form.

Received a 1.75 in my analytic geometry 3 years ago when i listened to your videos. Now I have graduated BS EE and I'm back to review for my board exams thank you so much ProfRobBob :) your awesome

[@profrobbob]

Thanks for all your continued support...we really appreciate repeat viewers and hope that you continue to share this free resource with everyone:D Go pass those board exams like BAM!!!

[@raultorres847]

Please don't stop teaching. You are the best.

[@profrobbob]

Thanks for sharing your appreciation Raul Torres It's good to see you are enjoying your learning experience with #ProfRobBob so much and I hope I can continue to help you throughout the school year:)

[@anluverbrandes8869]

The thing with your videos is that... IT IS NOT BORING.... IT'S COMPREHENSIVE... I'm Filipino and I share your videos to my classmates........ continue sir! God Bless

[@Baleion]

Thank you again for taking the time and effort to present high quality lessons online. I watch your videos just about every day. Top notch!

[@thebassofmontecristo]

Once again, being the best at what you do! Thanks, Mr. Tarrou! Curiously, I found that working with ellipses was not as difficult as I originally thought. I could do all my exercises and even found an equation for the orbit of the Earth around the Sun. Nothing beats that nerdy feeling!

[@profrobbob]

That calls for a BAM!!! Rafael Montecristo

[@profrobbob]

WOW...you are sure making me proud by watching all these videos!!!

[@harvestjoy3071]

My math teacher believes in "productive struggling" aka he doesn't show us how to do anything step-by-step. This video helped me learn so much! Thank you and I'm definitely recommending your channel to my friends!!!!

[@profrobbob]

+Harvest Joy thanks for studying, sharing and subbing...sounds like you should share my channel with your teacher as an additional study reference for the rest of his classes...we ALL get help that way:D

[@aarond7329]

Thanks for making this video! It's nice to see someone slow down and teach things the right way. You just earned another subscriber. BAM!!!

[@profrobbob]

THANKS Aaron D. for taking time to "thank the teacher" and share your support! Please continue to tell everyone looking for math help to do the same:)

[@pablo-sj5cc]

Well, 32 minutes 33 seconds well spent. Thank you sir!

[@profrobbob]

No I don't, but if you go the homepage of my channel you can use the magnifying glass under my banner to search just my channel. I can tell the way KZbin is working for me, Google is doing some kind of updates or something as well. It keeps changing my login to another Google + account I don't use for my math channel:/ Thank you for watching and your support though:D

[@barperetz77]

Your videos are amazing i wish you could be my math teacher. You have got me through every sigle test the past 2 quarters. Only if I had known you before... Thanks a lot

[@faithisabel25]

BAM ! ! ! Cant survive PreCal without your videos :-) Thank you for posting !

[@profrobbob]

Don't forget to keep sharing this channel with all the math teachers and fellow students:D

[@ceonrodriguez3867]

oh my, I completely agree! can't understand a thing of what our teacher has taught us. THANK YOU SO MUCH SIR TARROU!

[@profrobbob]

I don't think I have done a video with that example...but you plug each of your thee points into the general form to set up three equations. Then you can use matrices with either the Gaussian Elimination Method or Determinants to solve for D E and F. I have videos for solving three variable systems. There are other methods of solving but I don't have videos for those. I hope this helps.

[@GeoTedify]

I PASSED MY PLACEMENT TEST!!! BAM! You are awesome..

[@profrobbob]

CONGRATULATIONS on your accomplishment!!! I am very happy for you:) I know there was a lot of work on your part behind that grade.

[@peevestheprefect]

Thank you so much for all the videos you've been making! When I don't understand something in class I know that I have these videos to help me. Learning from your videos actually makes me enjoy doing math, which is extraordinary considering how much I've despised it in the past! You also have helped me get the A's that I've earned in class, so thank you very much for your videos.

[@davidhunsicker9953]

I have an Indian professor, and the accent and grammar less than facilitates communication shall we say. Thank you, this was very informative.

[@profrobbob]

[@brandonchao950]

First and foremost "THANK YOU" for this video. Without this video, I don't think I would of grasp the "Conics". This is however is the last exam of my semester and it is covering conics and equations and I thank you for this video.

[@profrobbob]

I wish I could be more help here:( I don't recall off the top of my head dealing with these types of problems in my class. Thank you for subscribing. I appreciate the support very much.

[@johncarlensen122]

used this to review for finals, easily recalled all my knowledge on ellipses, thank you

[@profrobbob]

That's what I'm talking about..."total recall" and ready to go pass those finals like BAM!!! You're welcome John Carlensen and thanks for subbing and learning from #ProfRobBob ....please keep spreading the word!

[@moemixlol301]

THANNNNKKSSS PROFROBBOB! Your vids have been helping me since the beginning of my precalc class but I haven't posted a comment since! I realized how helpful you are and wanted to thank you for all the support! Thanks a tonnnnnnn

[@profrobbob]

You are wellllcoooommmmeeeee!!! Thanks for taking the time to "thank the teacher" and subscribe!

[@moemixlol301]

I liked and subbed! Btw I'm trying to make a program that graphs all of these functions using java and without you're help in understanding how the functions work, I wouldn't be able to make it! I'm definitely crediting you when I finally publish it!

[@profrobbob]

MoeMixLOL That would be awesome and very much appreciated! Good luck with that project and keep me posted on your progress. My wife and I work very hard to groW my channel and our dream is to someday see a "M" next to that subscriber number so everything helps in achieving that dream!

For a second I thought you were my cousin...she loves to dress her cats:) Thank you for this extraordinary compliment! And yes I have heard the words before, but I never get tired of hearing how much these videos are benefitting people "everywhere", in ll walks of life...it's really still quite AMAZING!!! Building my channel has now become like a second job for both myself and my wife. We hope the saying stands true "Build It, And They Will Come!" THANK YOU from us both:))

[@georgesadler7830]

Professor RobBob, thank you for a beautiful explanation and classic selection of Graphing Ellipses and Circles. Students should find this old material fairly easy to understand in different levels of Mathematics.

[@profrobbob]

You're welcome and I'm glad this video was successful in helping you finally grasp the "Conics"! Now BAM!!! go pass that final with the additional knowledge I've supplied you with and make me proud:D

[@rialin]

Going through your conic sections, they are very helpful. The first time we were introduced to them, we were literally handed worksheets and told to study them and do example problems on our own. It was terribly confusing. But this clears it up. :) Fun story, a kid in my class would pronounce "foci" as "fo-chi" and while it annoyed the heck out of me, it would make me laugh all the time. Thanks again!

[@monevanderlinde8302]

Your videos help me so much! I don't know how I would have passed my exams without these videos :)

[@profrobbob]

Got 38 out of 40 and some Clapping for myself in class.. it feels good to get the burden off my chest .. now i am preparing for Finals .. i have a lot of syllabus and a lot of formulae .. having problem remembering them but trying my best..

[@profrobbob]

+TheHarshprasad BAM!!! Nice job!!! I always recommend my students make flash cards with the formula on one side and the name on the other, important facts, etc. Also you could practice writing a formula sheet over and over, then once you are given the test dump out all the formulas you need on the top of your paper before you start. Make sure your teacher knows you started with all blank paper first!!!

So thank you so much for being so awesome :P Don't get me wrong, I'm not trying to say my teacher is a bad one, I'm just saying that the way you teach is really efficient and most importantly entertaining XD. You probably know this already from other comments, but you've certainly made a huge impact to others like me.

Thanks for watching! That language barrier can be tough but remember where to find me if you continue to need extra help...and it sounds like you should share my channel with your classmates too:)

[@profrobbob]

THANK YOU for watching and including me in your success story and sharing your enthusiasm! Maybe you should start a campaign to get the word out to the rest of the world telling them where to watch and learn from "Tarrou's Chalk Talk":D....LOL, but really, any support you give my channel is appreciated in order to get the word out and help my channel groW!

[@profrobbob]

@ancvl Thank you I will be fixing that soon!

[@arkonfiftyone]

Mr. Tarrou, your video lessons are a life saver. I have spent an excess of 120 hours doing homework and trying to learn trigonometry on my own at my local community college. I don't like to point fingers, but my teacher is straight garbage. My question is in regards to determining values for an ellipse. MyMathLab has told me that when an ellipse is in standard form, and the center is NOT the origin, finding the vertices is different then when the center is the origin. I have in my notes that when a squared is under the squared y term (vertical), and the center is not the origin, the vertices are (h, k+a) and (h, k-a ) and then when the center IS at the origin, and the a squared term is under the squared y value (vertical), the vertices are (0, a), and (0, -a). Can you please help me understand if this is wrong or right? Thank you so much for all that you do. Jason

[@arkonfiftyone]

Now that I am watching your video on hyperbolas I see that you mentioned my specific question. I heard you say that and it was like you directed that towards someone like me. Well, it is honestly easier for me to just memorize a formula like (h, k+a) instead of counting the points on the graph every time. I always write out a formula sheet when I take my exams as a reference page. I think I honestly just confused myself, or the fact that MyMathLab doesn't stick to one form of the formula (meaning it gave me two different ones for the same thing) confused me. Also, the fact that that one equation for a parabola opening up/down is X(squared)=4py is confusing in itself. This just seems counter intuitive unless you draw it, which I haven't been doing much of until yesterday. Because when I think of something vertical, I think of the Y coordinate, which you pointed out very specifically in your video on hyperbolas :P. Also like you said there is a lot to memorize with conic sections, and I the best piece of information I have taken away to help me understand these differences on a coordinate plane, is to draw the picture. Thank you again. Jason

[@arkonfiftyone]

Clint_Beastwood Mr, Tarrou, I hope my second comment didn't sound like I was being a jerk. I did not mean that at all. Just messing around a little bit. Talking on the internet can be interpreted the wrong way and I wanted to extend you the courtesy of knowing that I was not intending to sound like a jerk. Alright, I have homework to do. Thanks again!

[@profrobbob]

Clint_Beastwood Not at all!!! The formulas that MathLab are technically the same, but when the center is the origin you don't have to write the h and k in (h, k+a) and (h, k-a ). I used to write a formula sheet before starting my tests too, that is a good test taking technique. I encourage my students to write out the formulas they need as they start their tests too. I hope you end up with an A in your math class and I am very happy I can help. Thank you for watching and your support.

[@arkonfiftyone]

ProfRobBob Thank you Mr. Tarrou. My final is this afternoon at 2pm. There is SO MUCH I need to remember for this exam. Here is the deal with how this class is structured at my school, the tests are worth 85% of your grade, and there are only 3 of them, and then the final. HOW WHACK IS THAT?!?! (In all seriousness it may not be that far from reality but the kicker in my situation is that my teacher doesn't teach us anything). So essentially, this teacher is having students repeat the course multiple times. I had a 90% average before the first test. After the first test, which I made a 68 on, my grade dropped to a 68%. I have been pulling it back up ever since. I made a few sign errors and put a few values in the wrong places and boom. As of this morning, I have 144 hours logged on my math lab for this class alone, and that is not including class time, time in the tutoring center, and other time spent when I have been logged out of math lab. My average as of this morning is a 78.5%. Since the final replaces our lowest test score, and it is a new test score on its own, I am hoping I can really improve my grade today. Your videos have been such an amazing resource to utilize I have recommended you to over 5 people in my class. Thanks again!

[@profrobbob]

Clint_Beastwood I hope by the time you are reading this that you have passed that final like BAM!!! Let me know… I give more than 3 tests and my tests are heavily weighted like your teachers. ..but I teach in the classroom just like I do on KZbin. I hope that my channel has helped you at home enough to bring that grade of yours up…& not for the lack of a lot of hard work and many study hours, I might add! Thanks for supporting my channel and sharing with your friends…keep sharing, I want to see a "M" next to my subscriber # someday:)

[@profrobbob]

BAM!!!...I love that you love my videos:)

[@alaome4233]

Excuse my curiosity sir.But in the 15+ min of the video, the standard form of your equation is ...(y+3)2... but the standard form of an ellipse is (y-k)... Is it still considered even though the standard form of an ellipse is negative and your equation is positive?

[@profrobbob]

That just means that the y coordinate of your center is going to be negative.... (y-(-3))^2 Thanks for watching.

[@OscarJTrump]

What video do you have for finding the standard equation of a three-point circle? It involves this type of equation: x2 + y2 + dx + ey + f = 0

[@marksibulan2384]

sir i guess 9/4 is 2.25?.... however your show is very good, it helps me a lot in my assignment.. pretty sure i will passed my demo teaching because of this show...

[@profrobbob]

Yes 9/4 is 2.25 but the square root of 9/4 is 3/2 which equals 1.5 I hope you pass your class and or test:)

@ProfRobBob Hey, professor! Could you make video series about VECTORS in mathematics. I received a poor grade from high school in this subject and would like to brush up on stuff. I never did very much physics in high school sadly either, so I never got the knowledge from over that subject either.

[@profrobbob]

I don't do a tremendous amount of work with vectors in the high school classes I teach. This page has the vector lessons I have done so far:) www.profrobbob.com/pre-calculus/vectors I am currently working on building my Alg 1 playlist while I'm teaching 4 different math subjects at my local high school.
