Let M be the capped cylindrical surface which is the union of two surfaces, a cylinder given by
x² + y² = 36, 0 ≤ z ≤ 1, and a hemispherical cap defined by x² + y² + (z - 1)² = 36, z ≥ 1.
For the vector field F = (zx + z²y + 7y, z³yx + 3x, z⁴x²), compute ∫∫_M (∇ × F) · dS in any way
you like.
∫∫_M (∇ × F) · dS =
