Quick question: Derivative of a Trig Function

[momogiri]

Question
Find the derivative of the function. Simplify if possible.
y = sin-1(2x + 3)

I'm wondering if the derivative is as simple as \frac{1}{\sqrt{1-(2x+3)^{2}}} XD

you forgot to multiply by (2x+3)'.

(arcsinu)'=\frac{u'}{\sqrt{1-u^2}}

OMFG BOB YOU'RE BACCKKKKK <3333 XD
My assignment is already overdue, so I can't do anything now XD

So it'd be
\frac{(2x+3)'}{\sqrt{1-(2x+3)^{2}}} to solve?

Indeed (http://en.wikipedia.org/wiki/Chain_rule), and it will hardly make the answer less simple :smile:
