Find the arclength of the curve given by y= integral from -pi/2 to x of sqrt(cost)dt. X is restricted between -pi/2 and pi/2.

2. Relevant equations

L = Integral from a to b of sqrt((dy/dx)^2 + 1)dx

L = Integral from a to b of sqrt((dy/dt)^2 + (dx/dt)^2)dt

3. The attempt at a solution

I'm not even sure how to start this problem since integral of sqrt(cost) has no simple function representing it. Can somebody please give me some direction?
