    Parametric equations of the surface of revolution? Not sure how to approach this..

    Can't even get started, any help would be appreciated. I'll probably need a couple pointers in the right direction along the way.

    Determine the parametric equations of the surface of revolution obtained by rotating the curve in the xy-plane given by y=sinx for 0<=x<=pi about the x-axis using x and the angle theta through which the curve has been turned as parameters.

    answer: x=x, y=sin(x)cos(theta), z=sin(x)sin(theta), 0<=theta<=2(pi)
