Question

Derivative Inverse Trig.
f(x) = 4arctan(pi/sqrt(2)
(formatting in reply)

Answer 1

Woops don't forget the x when you format it ^^ I notice it's missing in the description.

Answer 2

\[4\arctan(\frac{ x }{ \sqrt{2} })\]
I know the basic derivatives of the trig functions, such as arcsin(x), but the different expression within the arctan function is tripping me up.

Answer 3

How about derivative of arctan(x) ?

Answer 4

woops, I accidentally typed pi in the original post. The formatted reply is correct.

Answer 5

Ok here's a couple silly examples that will help maybe.... maybe not though XD
If you know the derivative of arctan, try to apply this idea to it :D
