cos( (a) Evaluate the integral Sp FdA where F(r, y) = and D is the triangle with vertices (0,0), (1,0) and (0, 1). %3D (b) Evaluate the integral: ry*dxdy by separation of variables. (c) Evaluate the integral ſ Sp V² + y²dA where D is the circle at the origin of radius 6, by converting to polar coordinates.

Let R(r, theta) = (r*cos(theta))er (polar coordinates) How do I find v (velocity) for r = 2, theta = pi/4, dtheta/dt = 2, and dr/dt = 3?

•LS -1 JO 1. Use polar coordinates to evaluate 1-x² (x²+ y²)³/2 dy dx.
