Chain rule for derivatives, with product rule (KristaKingMath)

[@anthonycostanza1119]

Too pro. I love people like you who take the time to make these videos. The payoff for humanity is huge. Thank you fellow human being

[@wayneeternicka4918]

I can't believe you positively responded to almost every comment. You are like the most attentive tutor on the whole net!! But it must be nice to know you provide such a helpful service. Thanks bunches.

[@sangeetagohil2377]

The run through with the simplifying was the best I could find on KZbin! Thank you so much! :))))))))))))

[@loveislife77]

When I'm feeling down I just come here to listen to Krista's voice. I hate math and Krista makes it seem like I'm listening to the most amazing stuff on earth.

[@AlliSanchez-i7c]

I have watched and read several articles on this rule and your presentation is the only one that makes sense. Thank you!!

[@benjaminharrison232]

Your videos have been a huge help! Back in '06 I failed precalculus after my third attempt and switched to liberal arts- but now I'm studying financial economics and getting A's on my calculus tests!!!

[@kizzzzie]

you just explained my professor's 2 hour lecture within 9 mins - I FREAKING LOVE YOUH!

[@Dontworryboutit247]

honestly....this is better than khan's video on this topic...Bravo krista, great effort dear, keep it up!!☺

[@kristakingmath]

Thanks! I'm glad you liked it!

[@hg2.]

That's right Ali. I never miss a chance to say "Krista is the best teacher on KZbin", one reason being that if all the other KZbin teachers copy her methods Exactly, the world's GDP will rise.

[@charlesrlassiter]

Dear Krista (Calculus Expert) I truly cannot thank you enough for your EXCELLENT abilities with helping me with the "Chain Rule for Derivatives, With Product Rule. Unlike many of the on line (and college Calculus professors) YOU leave them far back at the "starting line." Krista your piece-by-piece explanation is absolutely superior. Thank you ever so much!!!! You have no idea how much you have helped me. I am not a student, however, I just have a love for mathematics (am disabled with severely painful spinal disease) . I started Algebra I and later completed Algebra II and enjoyed them so much. Your great knowledge and teaching abilities are just fantastic!!

[@kristakingmath]

+charlesrlassiter Thank you so much, Charles! I'm so glad I'm able to help, and that you're enjoying the videos! Keep your passion for math and keep learning. :D

[@kristakingmath]

I'll continue to make more, but you can find the others here. :) youtube . com/course?list=EC1CDF4BF496C30885

[@tkdwar76]

I understood how to use the product rule, but I found myself stuck at the point where you have pull out a factor and simplify... I had no idea you could do that! This video has helped me a lot... thanks heaps and keep up the awesome work.

[@muhammedkanji]

Where, oh, where were you when I needed a math teacher in high school? Not that I'm having better luck in University...Stupendous! I've learnt more in a few hours of KZbin videos than I did in 4-6 months doing differentiation in high school.

[@kristakingmath]

Glad you liked it! :)

[@kristakingmath]

You're always so supporting! Thanks! :)

[@wimmaldo5868]

I love how you explain everything so clear. What you do in a couple minutes my professor takes over 1hour and still NOT clear..

[@peculiarnurd8841]

This was the exact question I got for homework. Bless!

[@leslieleslie336]

lol

[@kristakingmath]

you're welcome! i'm so glad the video made sense, and i'd be happy to be your professor on youtube!! :D

[@renie2578]

This video was amazing and so clear! Thank you for doing these videos and I hope to see more, please don't stop! Your concept is the best so far that I have seen. Can't wait to keep learning from you (:

[@kristakingmath]

Thanks for the kind words! I really appreciate it. :)

[@MikeH-ho7lm]

Krista, your videos have helped me tremendously in learning calc. You have a gift for teaching the abstract in simple clear language.

[@kristakingmath]

Thank you! I'm so glad to know that the videos have been helping! :D

[@Gibbs2135]

Finally...someone who can speak to normal people!!! I am normally the person who just gets things with all types of mathematics...for whatever reason, this chain rule thing threw me for a loop and I have been lost for over 2 weeks now. Well, you saved me with this video! Thank you so much!!!!!

[@kristakingmath]

Because you're taking the derivative of 3+x-x^2 to get the 1-2x. Multiplying by -2 would be taking the derivative AGAIN, this time of 1-2x, and you don't need to do that. I hope that helps clarify!! :)

[@MrOfficialUnofficial]

I just found this channel today and it makes calculus seem too easy! Great teacher!

[@kristakingmath]

+Very Merry Dingleberry Thank you so much, I'm glad it's helping!

[@erickendall2506]

Thanks heaps. I learnt more in 9 minutes than I did in an hour long tutorial. You are a natural at this.

[@kristakingmath]

Thanks! I'm so glad I can help.

[@shogo3564]

Finally someone took a moment to explain this stuff, not just blindly solve it. Qute as well:) Thank you so much! this video is most helpfull! Espetially for someone who skipped as many lectures as I did:)

[@0112838012]

This Is AMAZING !!! I'm an Engineer and i'm really so needy for the calculus as i started a course which totally depending on calculus and i couldn't remember it ! it's something since 6 years , so now i feel really i got it back to my brain ! thank you very much and everyone who's helping others ! Keep Going (Y) !

[@yenrabenahs]

My teacher is really confusing and talks over my head I'm in class. Help comes from unexpected places sometimes. Thank you so much and keep the videos coming!

[@perlahernandez9419]

I've been stuck on this problem for almost 4 hours!! THANK YOU SOOOOO MUCH! Life saver!! :)

[@kristakingmath]

Yay! So glad I could help. :)

[@kristakingmath]

yes, you need to use product rule, treating (x+1) as one function and (x-3)^2 as the other. as you're implementing product rule, whenever you have to take the derivative of (x-3)^2, you need to use chain rule to get it's derivative. :)

[@kristakingmath]

it's a rule you use to evaluate derivatives and integrals. it's like product rule, quotient rule, etc. for derivatives. :)

[@georgepolasky9809]

Thank you once again, Krista, for teaching such an important concept to us in your own wonderful way, as always.

[@kristakingmath]

So glad you liked my style! Just the fact that you "liked" my video once means a lot to me. :)

[@richiekrauss7993]

Your videos are absolutely the best. I had a gap between Calc 1 and Calc 2 and this has been a lifesaver as a refresher.

[@kristakingmath]

I'm so glad I could help!

[@jasonmoses6822]

Thank you so much for this video! I kept getting stuck on this type of problem but finally realized my issue is that I was not factoring! Such a big help, I'm saving this video. Please keep them coming!

[@kristakingmath]

+Jason Moses I'm so glad it helped!

[@kristakingmath]

I'm so glad they're helpful!! Thanks for saying hi!! :)

[@delaneyraymond6909]

Helped me understand this concept perfectly! Thank you for explaining so well!!

[@kristakingmath]

I'm so glad you found it!! Hope it's helping!! :D

[@PKJ8W]

i agree with everyone ... you're an amazing youtube teacher ! i actually learn and understand more from you than my teacher :p i didnt understand the chain and product rule together BUT you've reeeally helped me a lot ! keeeeep teaching and never stop (:

[@SilverArro]

I'm really loving your videos. I took Calculus 1 last year, and now I need to brush up to get ready for Calc 2. After searching through TONS of stuff on the internet, your videos continue to be the easiest to understand. I really appreciate all the time you must have invested into this. :D

[@kristakingmath]

Aw, thanks for giving me a big smile! :D I'm so glad they're helping!

[@YTooNClaN]

I watched this yesterday, didn't make sense. Watched this today, made sense! Thanks for the video, cleared things up!!!

[@kristakingmath]

+MusicLyrics101 I'm so glad it helped!

[@xInocencex]

+CalculusExpert.com how about finding the derivative of the function y=10 ^ (1-x^2)

[@Coffeehandle]

In my current Calculus class this was the most demanding part so far. Mainly because it requires a lot of multitasking. You have definitely cleared of up though with your video. Thank you so much!

[@kristakingmath]

David Alderman You're welcome, I'm so glad this helped!

[@kristakingmath]

Thanks for the support! :)

[@StreuB1]

Just started chain rule in class on Monday night and I was completely lost. I mean, DEEPLY concerningly lost! lol I watched the prior video and now this video, and it makes COMPLETE sense now!!! The idea that its power rule that leads into chain rule was so helpful. That literally was the "ah HA!!" moment for me. Thank you and FIY, I purchased Calc 1. I know it will help! Thanks Krista!!

[@kristakingmath]

Thank you so much Brian! I'm so glad this helped... chain rule is not easy.

[@deniselouisesteffen1315]

THANK YOU THANK YOU THANK YOU!!! You took the time to explain this and I have been struggling so bad with this! I am so grateful to you!

[@kristakingmath]

You are so welcome, Denise! I'm so glad it all made sense! :D

[@ralucius16]

So helpful. I have a calculus test tomorrow and had no idea what I was doing.

[@redeem5]

Thank you for the help. I don't know why I've never thought of factoring entire expressions before, but making that click will help me a lot in the future, I'm sure.

[@kristakingmath]

Oh good! I'm glad it helped! :D

[@beachguymiami]

Wow!! Amazing how easy you explained it. My professor is really good at explaining terms, but your method is much better. If I could like this tutorial and other that you made more than once I would.

[@emonypemony]

THANK U SO MUCH FOR THIS DETAILED EXAMPLE! u are so articulate and u went thru the example in a very systematic organized manner tht was so easy to understand! i wish u were my prof lool!!

[@ropperish]

Math on a soft voice, that’s a first. Thank you very much Kris, it was very helpfull

[@kristakingmath]

i'm so glad it helped!! good luck on your test! :D

[@froffiek]

This is the first time i've ever commented on a youtube video. I was struggling with a very similar problem for 2 days. This video cleared everything up in less then ten minutes. Thank you so much for what you do.

[@kristakingmath]

You're very welcome, I'm so glad it helped!!

[@kristakingmath]

WOW good for you, that's awesome!! I'm so glad it made sense and was clear enough for you to understand it so quickly!! :D

[@JAYDEEP1]

Great!!! Better explanation than my teacher! Keep up the good work!!! Thanks!!

[@kristakingmath]

That makes me so happy! I'm so glad this helped!! Good luck on your exam!! :D

[@implicit2656]

Great video if have just started the chain rule application!

[@ThabuffaloGamingHD]

AH! TY TY! I have Mid year exam tmr, I understood everything but had this jumbled in my head. I always did one rule but not the other, you made it so clear to me! Ur awesome!

[@shoubhikghosh8714]

Forbidden fruit is always the best! Have been bunking school to watch these videos! My 12'th grade maths exam (Before undergraduate studies, in India) starts on the 18'th of March. Thanks!

[@adamdee1867]

always so helpful, thank you now I'm ready for my calculus test

[@kristakingmath]

aww thank you so much!! :) i'm so glad this was helpful for you... and thanks for watching my videos!!! :D

[@Jer-33_3]

You have no idea how much your videos help me! I most certainly Praise Father God for the blessing that you are! And i thank you for having a generous and empathetic heart!

[@kristakingmath]

Thank you so much, I'm honored to be able to help!

[@kristakingmath]

You are so welcome! Thanks for the comment. :)

[@tannerbarcelos6880]

This is a really good problem. more complex and usign multiple rules. Much appreciated.

[@kristakingmath]

Yay! I'm so glad I could help refresh your memory! :D

[@kristakingmath]

if you need help solving that exact problem, try plugging it in to wolframalpha . com! it should give you the step-by-step solution and the answer. :)

[@brkfstofcmpns]

Your videos are realllly helping me with my calc class!

[@kristakingmath]

Yay! :D

[@afvetvenom3685]

This greatly improved my understanding of the chain rule. THANKS!!!

[@kristywilday3205]

Oh my gosh, you just explained it beautifully! I think of all the videos that I have watched,, you have explained it the absolute best. And you don't speak fast, so I could undersitand you perfectly, When I was doing homework, I kept getting confused, and I don't think that will be an issue. Thank you!

[@kristakingmath]

You're welcome, Kristy! I'm so glad it made sense! :D

[@2tonesg]

I had a long message but suffice it to say that you have my gratitude for making this easy to follow. I bought your Calc 1 course but didn't get through it before the semester started, so now I'm looking up concepts as they come up in class. Thanks again.

[@kristakingmath]

I'm glad I can help along the way! :)

[@angelicadayucos5314]

omg! have to report tomorrow and i began to cram where to look for help, i browsed, and browsed...i almost gave up but then i saw this! AMAZING! THANKS!!! You are a gift from Above ^^ Godbless!

[@ryanwalker4491]

Thank you very much for this wonderful video! You make Calculus easy to understand, and you're one of the reasons I scored a 103 and 95 on my first two exams :)

[@kristakingmath]

That's so awesome! You still had to put in the all of the work. But I'm glad I could help. :)

[@kristakingmath]

That makes me happy! Thanks for letting me know! :)

[@adrianophilo391]

at the beginning of this video I realized I had watched this one already; more the once, actually; but because I liked it so much, I watched it again anyways. Unfortunately I'm having trouble with that kind of rational fraction equation I wrote about (y=600x/300-x). But I really appreciated your fast answer and all the videos you've provided. Thanks a lot for the best wishes on my test.

[@kristakingmath]

You're welcome!

[@kristakingmath]

You're so welcome! :)

[@Goshenrooftopgardening]

Integral Calc, This is brilliant!! You are simplifying many peoples lives and indeed changing the world in your own special way. Naphtal

[@kristakingmath]

Aw thanks! I'm just glad I can help. :)

[@APjohnflores]

[@kristakingmath]

I'm glad it helped!

[@kristakingmath]

That means so much to me! Thanks for letting me know. :)

[@saskatoondownpour1000]

Thanks, very well explained and easy to understand. Very much appreciated!

[@kristakingmath]

You're welcome! I'm so glad it helped!

[@kristakingmath]

aww thanks!! good luck on your test!! :D

[@omkars764]

hey, when you were factoring things out, why were you able to take common factors and just leave (1-2x) alone? Wouldn't the factors have to be compatible with (1-2x) as well?

[@adrianophilo391]

Hey Krista! How R U doing? This coming Monday I'm having a test and I'm pretty sure I'll find a equation as the following (y=600x/300-x) to find axis, hyperb., asympt, etc. I wonder if you could be so kind and solve this one step-by-step so I'll never forget how it is done? you fan, Adriano from Brazil.

[@kristakingmath]

Good luck on your test!

[@weenyhutjr.6654]

Thanks so much!!! Very helpful and you did a great job!

[@kristakingmath]

Aw thanks!

[@MegaAladin7]

Thanks a lot! Really helped me for my Calc test preparation.
