    Why is the derivative of absolute value of x (x*x')/abs(x)

    Yeah, I tried explaining that to my calc teacher and he just said that it was incorrect because they were not the same. At the time I did not realize I could prove the abs(x)/x to be equal to x/abs(x) so I just let it go.

    Why is the derivative of absolute value of x (x*x')/abs(x)

    Still have to prove that my answers right to my teacher though. Thank you again. I know it might seem stupid but this question had been bothering me for a while and finding out I'm right feels good.

    Why is the derivative of absolute value of x (x*x')/abs(x)

    Yeah sorry. I meant the derivative of x being x'(x/abs(x)) also being equal to x'(abs(x)/x)

    Why is the derivative of absolute value of x (x*x')/abs(x)

    Great. Now I just need to get that into the head of my Calculus teacher. Thanks!

    Why is the derivative of absolute value of x (x*x')/abs(x)

    So why would abs(y)/y be considered incorrect for the derivative of abs(y) if you say they're equal?

    Why is the derivative of absolute value of x (x*x')/abs(x)

    I have no problem that I am trying to solve but simply a question about the derivative of an absolute value equation. I know that the derivative of and absolute value function is (x*x')/(abs(x)) and I understand the process of reaching this equation through the process shown here...
