[@profrobbob]

And Thank You for saying so...and for showing your support and subscribing! Please help my channel grow by sharing with others:D

[@salmanali5992]

You are a life saver. I cannot understand my math professor whatsoever. Thank you for taking the time to make calc understandable.

[@profrobbob]

+Salman Ali and thank you for taking the time to study and sub to my channel:) Please tell all your classmates to watch and do the same:D...and keep sharing that great smile!

[@profrobbob]

Yes I do. Type in asymptote in the search window on my Chanel's homepage. I have a 2 part video for graphing rational functions, another for finding vertical asymptotes and holes, and finding horizontal asymptotes of irrational functions.

[@Zerohanaa]

You have saved my life Mr. Tarrou! I wouldn't have passed my classes without you. My professor doesn't explain it as crystal clear as you do so thank you for doing this =)

[@profrobbob]

And you never would have found my videos if YOU had not taken the time to find extra help on KZbin and chose #ProfRobBob to learn from...BAM!!! You can help us back ***** ...Please remember to like, subscribe and share my channel with others to help us keep growing:D

[@profrobbob]

Great job...and thanks again for paying so much attention that you help to keep my videos correct:)

[@EP-rq3pn]

Nailed it! (The problem at the end) Thanks to you Mr. Tarrou! It's so helpful that you not only do you clearly explain how these concepts work but that you give us several examples to work through.

[@profrobbob]

Thank you. I can’t bring myself to just make 2-5 videos that may not help the viewer develop a deep understanding of the mathematics. I appreciate your positive feedback. Hopefully you have discovered that I put time stamps in the description to help you jump ahead when desired.

[@profrobbob]

You are so welcome...Thanks for choosing my channel to learn from!

[@geogaddi84]

God, I wish you were my professor. I am doing an assignment where I HAVE to use the quotient rule, but your over all methods are so good that they were able to help me get past a problem that I've been stuck on ALL DAY!! ProfRobBob for chairman! BAM!

[@profrobbob]

+Adam Chavez at least I can be your YT teacher, thanks to you making the decision to study thru YT:) It's always nice to hear from loyal subscribers like you, that theses lessons continue to help so much...BAM!!! As for that chairman position...how about if you be the president of my YT math teacher fan club and start spreading the word thru social medias, like me on Facebook, and ask everyone to like, support the ads, SUBSCRIBE and tell all their friends to watch and do the same...I'm in a race with Hip Hughes to see who can get to 100,000 subscribers first...and we can't let history beat out math can we?!

[@profrobbob]

Thanks for watching!

[@xXDJBANXx]

I just want to say thank you for the time and effort you put into your videos!!! I have been watching your videos since trigonometry and I am now a first year calculus student. I can not tell you how much it has helped me to watch your examples! You are a great teacher and I appreciate the work you put into helping math students succeed. Thanks!!!

[@profrobbob]

+Zane Tatum you're welcome and thanks for taking the time to share your appreciation and for choosing my channel to watch and support! Students like you are why we keep working so hard to grow this channel...as a teacher, it's very rewarding to know you are making a difference students lives:)

[@marieedwards5512]

Thanks Sir you have made my assignment so easy for me to understand and to complete on time. Best teacher I have come across in my entire school life. Keep the videos coming.

[@profrobbob]

Thanks MARIE EDWARDS for taking the time to "thank the teacher"! You were the one that decided it was important to study and I'm happy that Tarrou's Chalk Talk could be a part of that learning experience:) I'll keep making videos as long as you keep telling all your friends and classmates about my channel, to SUBSCRIBE & like, Like me on Facebook, and share with all their friends and that will help my channel groW and continue to help others...BAM!!!

[@marieedwards5512]

Bam

[@londospark7813]

Thank you for this Rob - most teachers here won't show the simpler way of doing things and insist on the quotient rule even when it's inappropriate!

[@profrobbob]

+Gareth Lees (ridecar2) you are welcome! ...and thanks for choosing my channel to learn from and sub to:)

[@alwayslit_texting]

AT 10:09, HOW IS X^-3/2(X-1/2) TRUE? IF YOU MULTIPLY IT OUT, IT SHOULD COME BACK TO 1X^-1/2-1/2X^-3/2 WHICH WAS THE ORIGINAL FORM WRITTEN WITH THE NEGATIVE EXPONENTS TWO STEPS ABOVE IT, PLEASE HELP

[@profrobbob]

It does return to the form two lines above. x^(-3/2) * x = x^(-3/2+1) = x^(-1/2) for the first term

[@sargerpd]

Mr. Tarrou the BEAST.

[@profrobbob]

BAM!!! Good to see you're still watching, learning and supporting ***** :)

[@sargerpd]

ProfRobBob And i will continue to support your channel cause you actually take the time to explain to the mathematically challenged students =D

[@viarg1va]

I would just like to say your video's are so helpful and your enthusiasm makes the so much better.

[@edersantos1735]

ProfRobBob ... thank you for this video!!!!! I wish I more professors that could teach like you. :) Life saver !!! much easier to understand the subject by watching your videos ...

[@profrobbob]

Eder Santos you're welcome!Thanks and please like, subscribe and tell everyone to watch and do the same to help these free educational channels reman free and so others can share the same learning experience with you:D

[@shipwreck9146]

I think it's funny that before this video, I got an ad about online tutoring, and it was saying that these types of videos don't help. Then I watch the video and it's fantastic thank you

[@irfank20a29]

i have finals in a few days and this video really save me a shitload of stress and confusion. THANKS. your virtual class really saves me. Keep it up! :D

[@profrobbob]

Irfan Comot you're welcome and thanks for liking, subbing and learning from #ProfRobBob Please share my channel and your experience with everyone and remind them to do the same to help these free educational channels groW and remain free:D

[@ocs5]

at 9:07, you said, "bare with me here, I'm going to do this verbally....-No i'm not!" You totally could have just skipped the written work but you didn't. Thank you for taking the time to show the extra steps. And your videos are perfect.

[@profrobbob]

+Olivia Cabadas BAM!!! Thanks for studying and subbing and taking the time to share your appreciation...keep up the great study habits and thanks for choosing my channel to learn from. Please spread the word:D

[@SrishtiR0y]

Thank you so much for posting these videos and showing each little step. This was so helpful!

[@profrobbob]

+Srishti Roy you're welcome and THANK YOU for choosing my channel to learn from and sub to! SPREAD THE WORD :D

[@hizribagomedov4577]

man, you explain much better than my university teacher!

[@EilishBrennan]

do you have anything about asymptotes of rational functions? (like how to find them?)

[@mhelandycastro9860]

@12:52 sir.. would that be x^2+2?? bcoz when you divide x^3 by x the answer will be x^2 right? Therefore, the correct denominator for that will be x^2+2.. correct me if im wrong T ^ T im confused. Thanks!

[@matthewzarate9116]

😰 Umm.... 9:40? I really can't remember anything about factoring out exponents.... Whats the name of the rule you're performing? I gotta look it up.

[@profrobbob]

None of them are examples as complicated as what is in this video, but I am factoring out a common monomial, kzbin.info/www/bejne/gJu9m5KihL2Cg80

[@matthewzarate9116]

ProfRobBob Thank you!!

[@profrobbob]

:)

[@momid7056]

Great video and its hepl me so much... but sir i have question from 08:58 upto 09:33 min i didnt understand, because 1st you have taken (X^-1/3) commen and thn you divided how? Will you a little bit elaborate it? please.. thanks

[@profrobbob]

I apologize for not answering your math question until now. My full time teaching job is keeping me too busy! I hope you were able to figure out your question. When you factor out a common variable factor you can take out the lowest exponent.

[@jamiesong01]

i got it right! thank you, sir!

[@profrobbob]

YouMe Park BAM!!

[@aldo7962]

Thanks! i am just really confused on identifying what rule needs to be or should be used.

[@11McFlurry11]

+Aldo Corral Hey bud, if you're still in need of the help, if the function is in the form of a function over another (f(x)/g(x)), the, by the rules stated by profRob, the quotient rule will be used as the functions are in the format of division. Other than that, either the product rule and/or the constant rule will be used for other differentiation examples, looking out for the conditions pointed out in profRob's videos. Hope this helps :).

[@aldo7962]

+Richard Luiz It does help. thank you

[@kuso1426]

you are a consummate professional. Thank you so much!

[@profrobbob]

You're quite welcome…and THANK YOU for the compliment and for choosing, supporting and subscribing!

[@psalmco2425]

You a beast at teaching maths

[@profrobbob]

Thanks for liking, learning, studying and subbing and taking the time to compliment...please share with your classmates and teachers too:D

[@ch0vits]

I still dont get how you simplify sir the 2 - 1/X in the last example.. heelp! need a dummy explaination :(

[@profrobbob]

2/1-1/x, to add or subtract fractions you need a common denominator...so multiply the first fraction by x/x. x/x reduces to 1 to you are not changing the fractions value, just making it look different. The x came from the lowest common multiple between 1 and x.

[@ch0vits]

whoops..imma go back to this lecture laater :)

[@nicerackz]

can anyone help me understand why you can change one of these problems from quotient form to product form for the derivative, but not the other. 1) x/x^2+1 (requires quotient rule) 2) 3/x^2+1 (does not require quotient rule) why???? please help.

[@profrobbob]

Your first problem can be done in product form with the product rule, it is just more difficult.

[@chemrichx4161]

Hey rob, for f(x) = x^2 - 2x^3/x+2, can you take that 2 constant out before you derive? enjoy your vids by the way.

[@profrobbob]

That would have saved me from having to factor the 2 out at the end:P haha Thank you for the kind words.

[@chemrichx4161]

You're welcome and thank you : )

[@profrobbob]

:)

[@gordonpearson7736]

For the quotient rule: "Low d high minus high d low, square the bottom, and away we go."

[@tartantwinning]

Seriously thank you. Thank you, thank you. Amazing

[@profrobbob]

You're welcome, thanks for watching! You can thank me by subbing and sharing this free channel with your class and teachers:D

osama ansari thanks:)Don't forget to like, subscribe and spread the word to help us keep growing :D

[@anumivenkatesan4323]

thank u so much sir. ur videos r so helpful .

[@anathimostifa4167]

cant see the proofs of the rules

[@omarmajid8971]

Can you be nice and do f(x)= 2x+1/x^(1/2) with the quotient rule and not like you had been doing at the video

[@mayzuunmanzurih5961]

Thank u so much teacher

[@profrobbob]

You're welcome...thanks for watching!

[@sniperdude2222]

Dear god thank you so much.

[@kimonifrater1256]
