What is the derivative of arcsin(4x+2)?

Homework Equations

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.

 

[jumbogala]

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

 

[Dick]

Then it's just fine.

They'll give you an answer, don't be phased necessarily if they are not quite the same, often there are more than one possible answer or method, or they may have simplified it further than you.
