Inverse Hyperbolic Functions - Derivatives

[Goblinlorde]

Mr Patrick JMT you sir are the biggest legend of all legends. I hope you sleep easy every night thinking how much you have helped students get through university/college. Take care!

I don't understand why teachers can't just make it this easy.

[JesusMartinez-zuxl]

I know this video is pretty old but you made this topic easy to understand!

[carlykiller]

8:10 that sqrt(x^2) is suppose to be sqrt(-x^2)

[made]

I was wondering when you were simplifying at the the end (8:12), you simplified the square root of x^2 to x, but wouldn't it be the absolute value of x? That wouldn't be the same answer then, right?

This video's about 3 years old so I don't know if you still check these comments but I thought I'd give it a try.

I pay to go to school and have a professor "teach" me this - when in fact 100% of my calculus knowledge comes from Patrick's videos.... hmmmm...

[marcelkruger]

Thanks so much for the video (time 0:28) especially. Found out my entire page I was given pertaining to the derivatives was wrong,

[hoojks]

i LOVE YOU.
With all the calc2 proffessors @ my college having a rate my proffessor rating of 1.5 below and sucking. you will help me pass my class

Who's watching this on Sept. 12, 2018?

Hi! I just wanted you to know that your videos helped me a lot to understand things that I don't when it comes to calculus! Thank you. You're awesome!

[derickdewitt]

THANK YOU SO MUCH. I was using the wrong formulas until I saw your Video!! Thank you!!!

In the last problem, how the square root of x^2 becomes x while x from -1 to 1? Thank you.

How should I go about integrating 1/(1-x^2)? Came here looking for some help and found that both arctanh(x) and arccotanh(x) could be substitutes. Which one is it?

[imwithdumbhead]

at 2:44 you forgot to multiply everything by 2. (found in the last term; derived from 2x)

[lambertsempundu]

that's great job brother. keep it up.

[MeLol]

Help please integral of (csch (t^1/2 )coth(t^1/2))/t^1/2

The argument and denominator is actually square root of t.

[RichPerez]

Why does the absolute value of x have to be less than 1 for the derivative of inverse hyperbolic tangent but greater than 1 for the derivative of inverse hyperbolic cotangent?

[AlexanderAV]

Hey Patrick question; are you a student or a TA or something? All ur vids are going parallel to my eng. I course!

[ntandokazibaxana]

Thank you soooo much for Very helpful!

[lizchatham]

Hey, thanks for these vids. You're pretty awesome.

[zaproud]

hey many thnx for this lesson
but is there a cool way to sae theses derivatives in my mind and not to forget them ?
i hope you answer me
