Let u = e^qr sin-1p, p = sinx, q = z²ln y, r = 1 / z. Find the derivatives au / ax, au / ay, and au / az as a function of x y and z, using the chain rule and expressing u in terms of x, y, and z before derivatives. Then compute the derivatives du / dx, du / dy and du / dz at the point (x, y, z) = (π / 4,1 / 2, -1/2)
