Quick question: Derivative of a Trig Function

  1. Oct 15, 2007 #1
    Find the derivative of the function. Simplify if possible.
    y = sin-1(2x + 3)

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

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

    My assignment is already overdue, so I can't do anything now XD

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

    Indeed, and it will hardly make the answer less simple :smile:
