Graphing Parabolas in Standard Form

[@thomgrunauer6526]

I watched a bunch of videos on khan academy and read my textbook and could not figure this out. Then i watched this video and it became simple. Thank you for your videos you have helped me out a lot with studying for this clep test.

[@profrobbob]

Thanks for studying and don't forget to like and sub. I have a lot more videos, about 590 of them. They are all organized right here, www.profrobbob.com Good luck on your test, go pass it like BAM!!!

[@thomgrunauer6526]

Passed it on Monday, moving on to honors calculus 1 this semester now. Thanks again for the help.

[@profrobbob]

CONGRATULATIONS Thom! Please share my channel and your success with your teacher so they can share it with ALL current and future students so they know where to find free help like you did...BAM!!!

[@mirajones1295]

Khan academy is a Zionist backed organization. They aim to indoctrinate. Don't ever use them!

[@ghostfrom1950]

Khan Academy videos feel long winded and off base to me. I keep coming back to this channel because there is an excellent association to the actual mathematics rules and principles being directly applied to the unique material!

[@profrobbob]

I started making videos to help one of my students who was going to miss some class time....& now 422 videos later, I do these videos to continue to help more of the thousands of supportive viewers who have sent me comments thanking me for "making a difference". I love teaching & the reach that KZbin has opened up for me is extremely rewarding. It let's me share my passion for teaching math with the rest of the world...there is a some monetizing from the ads but I do it because I love it!

[@georgesadler7830]

Professor RobBob ,thank you for another basic method of graphing Parabolas in Standard Form. From reviewing Parabolas over the years, I always have some problems understanding this material, however watching this video, drastically increase my knowledge of the subject matter. I hope students continue to appreciate the fantastic teaching style on KZbin.

[@vineetdeepika]

Sir, The contribution of yours to this society by educating children is immense. Thank you for all your efforts and one more thing .... BAM!!

[@profrobbob]

Yipppeee...welcome back:) My lessons are currently organized on my channel page by subject and the order that they were taught in book & class. I tried to start working on a website during spring break but there just weren't enough days off!...it is on the toP of my list between teaching full time, grading papers and then teaching to the camera and producing new videos for my channel...but it is on the "list" of the next big thing to do! Thanks for the input:D

[@vivekjames99]

Your videos are amazing. I'm an 8th grader taking geometry and even though I haven't taken algebra 2 yet, your concept and teaching of parabolas makes it so easy to learn. Its great how energetic you are and especially how you "jump in" to teaching. BAM!!!!

[@profrobbob]

WOW...three fantastic compliments in one day! You really HAVE been doing your homework haven't you?! I must tell you that being a KZbin teacher has taken my teaching career to a whole new level and Compliments like yours are just another reason why I love what I do!...so thanks for choosing my channel to watch and learn from:)

[@wolfiedraws8464]

I just really wanted to let you know how much I appreciated these videos. It is the night before my final and I am...well was so confused on these Conic Sections. I feel so much more confident. Thank you!

[@raultorres847]

Man, you just saved my rectum! Thank you so much for teaching.

[@profrobbob]

And thanks for studying Raul Torres !

Now Closed Captioned!!! Graphing Parabolas in Standard Form

[@profrobbob]

You can change CC options. Click the Settings wheel, select Subtitles/CC's, and then options. You can change the background color to black and all kinds of other settings.

[@profrobbob]

Unless you are graphing y=x^2, your parabola has some type of translation. Y=2x^2 has a vertical stretch of two...if a parabola has a vertex of (-2,1) there is a horizontal shift of 2 left and a vertical shift of 1.

[@awesome5657blink]

You are the best! You teach the same as my math teacher, it's so hard to find videos with as much detail that you give in your videos. You also work out some of the harder problems that many people just skip over.

[@profrobbob]

THANKS for watching and sending this nice comment! I do say BAM in my class and hope you like this channel enough to keep sharing it with students and teachers and please remind them all how important it is to subscribe and share all the free educational channel that help you...that's how we grow and remain free...BAM!!!

[@profrobbob]

Thank you so much for sharing...And it sounds like you are making a "jump in" to some early learning! I hope you will continue to choose Tarrou's Chalk Talk for all your after school math teaching help, and be sure to share my channel with your friends and classmates and help me groW!...So BAM!...start sharing right away:D (I have my channel set up to approve all comments...that's why there was no immediate reply:)

[@VividhMehta]

I love the way you teach professor. Thanks a lot. Finally, understood all the concepts!

[@SuperJuansandoval]

you are a lifesaver. I was absent last class and this video save my grade...u rock see ya in calculus

[@profrobbob]

Happy I could help...don't forget to like, sub and keep sharing:D

[@profrobbob]

Most problems I have seen give you the vertex (h,k) and any other point the parabola passes through is a generic (x,y). You plug in those two points and solve for a, and then write out your final equation leaving in the x and y variables.

[@ashleybowen3805]

Thank you Mr.Tarrou!! You are literally saving my grade. I think I can tackle my homework now! Never stop teaching!!!!

[@carlosdeleon9593]

Wow. You're beyond awesome. I can't believe my pre-calculus teacher couldn't reteach this, but now I remember. Thanks.

[@123kaul]

i just learned more in this video than the last week of math class, some teachers cant explain things, you are defiantly not one of them, thanks so much for this video, it helped a lot

[@profrobbob]

+Gaurav Kaul you're welcome, glad it helped:) Please take the time to sub and share this free educational channel with your friends and classmates and remind them to like, sub and keep sharing to help us keep growing and helping others:D

[@Eze4383]

+ProfRobBob Thank you so much. I'm in the same class as Gaurav and he showed me and my group the vid. You juat earned yourself a sub. 👍

[@profrobbob]

+Emil Dantzler that's AWESOME!!! Please thank Gaurav for sharing and please tell your group to keep the shares and new subscribers coming...we set a goal again last year to reach 100,000 subscribers and even sent out a plea for help via a holiday video but we are still about 6,000 short:( Educational channels are hard to grow without the support of subscribers, but its been over 4 years now and we won't give up on that dream...BAM!!

[@beatrizehannas.brocal9062]

[@spikeroseman3992]

Latus Rectum is a Latin compound word. "Latus" means "side" and "Rectum" means "straight." Great videos. Without your help, i would have beaten my head to a pulp from beating it against the wall! My math professor needs to take notes from you.

[@maheshvra5995]

Mr. Tarrou, it's been a while since i visited your channel to study because my lessons are so easy but now it's really hard but thanks to you I did well in the exams, I'm an engineering student here in the Philippines. Thankyou sir!! :D

[@amariforeveryoung8789]

I had to pause this video to write this: *Rant I wanted to say that you are like the first math teacher I've met (on the internet I guess, well I am Generation X so...) that wasn't pretentious. You're funny but in a geeky cool way and I can tell you are actually enthusiastic about teaching and learning. Of course I've had teachers who say that they will be evolutionary and say that they WILL be understanding, and WON'T be condescending. But then they are. Yes, we know you get it, you understand it. There is nothing we can do about it if we don't know it, if we just don't understand it, if we didn't learn it last year, so, how about instead of harping on something we can't change, thus stressing out an already stressed out high schooler, we instead focus on learning right now. lol Sorry, not sorry. I had to rant. I'm sitting here, trying to do my homework. Barely knowing anything from an hour and a half long math class. I wanted to say thank you in advance.

[@profrobbob]

My motto is "Let's make Math FUN" while learning...sounds like I have inducted another believer:)...and that is the part that keeps me excited about teaching math! Thanks for taking the time to watch my video...and please share with others if you found it helpful:D

I can't imagine why you would do these. As a high school student that hates class, these are ideal whenever I don't know how to do something, however what's your gain? I can't imagine you get paid for these. And if you do it couldn't be that much. Do you do these simply out of the kindness in your heart? Do you have a goal of contributing to a better society?

The 1/4 that chose not to look is, how can I politely state this. Uhh they want to learn it in 4 minute videos, and unfortunately especially for Math some topics need more time. I have another friend who told me you got her through calculus, so don't worry we New Yorkers are tuning in. BAM!!!!

Thank you Bob!!! You're the best :D

[@electricteaching]

Some books call it the 'conjugate axis.'

[@Taricus]

"latus rectum" means "right side" (I'm assuming it's because the latus rectum forms a right angle with the side of p, extending from the vertex.

[@Taricus]

Also, if you said it like you do in Latin, it would sound like "lahtoos rectoom" :P

[@profrobbob]

Jimmy Amato Thanks for the insight...Students teaching teachers...BAM!!!

[@Taricus]

ProfRobBob I should add that it's backwards in Latin. Rectum is the part that means coming to a 90 degree angle
