D Dovud Dec 2009 9 0 May 11, 2010 #1 Hi! I can't figure this out: The point (pi/4,1) lies on the function in the form y= sin kx. Determine k. So I did: 1= sin k (pi/4) Is that right? If it is, how do I solve the equation?

If it is, how do I solve the equation? Click to expand... Next step is to take the inverse sine of both sides. Reactions: Dovud
