Problem. 4: Find the Jacobian of the transformation. -4r X = 2e Ə(x, y) მ(r, 0) and the transformation x= 8u and y = - 4r sin(50) y=e¹r cos(50) Problem. 5: Consider the region R in the xy-plane bounded by the ellipses x² y² + 64 81 9v. Compute a(x, y) d(u, v) - 1 SE a(x, y) d(u, v)

Problem. 9: Use the given transformation x = 4u, y = 3v to evaluate the integral. If 4 2² dA, R where R is the region bounded by the ellipse 16 || 42² 4A = R + y² 9 - 1. ?
