1. The problem statement, all variables and given/known data
What is the derivative of arcsin(4x+2)?

2. Relevant equations

3. The attempt at a solution
I just want to check that I'm doing this correctly; my teacher didn't give me any examples to try.

I get 4 / ($$\sqrt{1-(4x-2)^2}$$)

Is that right?
EDIT: Just realized I posted this in precal math, sorry!! =(

Why do you have (4x-2) in the radical? Typo, right? Otherwise, it's fine.

Whoops, it's supposed to say 4x+2. It's still supposed to be in the radical, though.

Then it's just fine.
