Calculus I: Derivative of inverse functions

[@daviddavid5143]

sir, you have made my day I have written all the lecture word by word so not to lose the information, thanks alot.

You're welcome!

You are doing an awesome work please keep it up . And be motivated.

At 23:56 we have an equation to be solved for the derivative of the inverse function. It appears that everything after the inverse F' is a calculation of the argument for that inverse derivative function. If thats correct (and this is where I may misunderstand how you solved this), how can we simply divide the final product, the argument, to give us the derivative value of 1/6 when that final argument is 30 & multiplication of an argument of a function, including the derivative function, by a scalar changes the horizontal scale of the function, not its y values when corrected for the scaling.

[@MathforThought]

You misunderstood. It's saying f^(-1)'(5) as in, I'm calculating that value for x=5.

i really enjoyed your exercises. many tutorials on this topic only teach how to juggle, iykwim. yours really tests if i understand the concept. i especially enjoyed having a post-obvious realization while doing your first exercise that i do not need to find an inverse function at all, i can just guess which argument fed to the normal function will give me the argument i would like to solve the inverse function for. very cool. :)

Thank you very much!

thanks for everythink sir

Audio excellent you are really helpful buy visually ,I’m disapoinyed

Great content! But you should consider changing the color scheme. Blue in black background is barely visible.

[@MathforThought]

I did change it to white later :) .

Will at some point questions get trickier than q2?

[@MathforThought]

I doubt it. That was a fairly difficult question.

[@bernardocarlo4608]

For question 2, is G’(2)= -1? U didn’t answer the question fully.

[@MathforThought]

I did answer it. Yes it's -1.

[@MaalikFaun]

forget what i just said. I LOVE U SO MUCH

[@MathforThought]

Lol thanks.

[@MaalikFaun]

30 minutes of pure ramble .. bruh

[@MathforThought]

You can skip ahead.
