I don't know what I did wrong... Find y' of y=cos^-1(e^2x) Ok, so cos^-1 is sec. Then I got sec(e^2x)tan(e^2x)(2e^2x)(2). Not sure if the (2e^2x)(2) part is right because the online hw keep telling me I'm wrong.

Mmm... be careful with the notation. -- You wanna compute You know that
So then I got sec(e^2x)tan(e^2x)(2e^2x). I'm still not getting it right.
You want to find the derivative of ?. Chain rule. The derivative of So, the derivative of Therefore,
