    simple integration problem

    Hi, this is a simple integration problem that is bugging me......find the equation for the curve with y'= 1/sqrt(9-x^2) and passes through(3,pi/7). I have done this before but its been so long I can't remember. If I integrate y' I'll get y= sin^-1 (x/3)+c ????? Can someone please point me in the right direction. Thank you.

    You're already going in the right direction. Now use "....passes through(3,pi/7)." to find c.
