Compute the outward flux of the vector field F(x, y, z) = 5xi + 3yj +5ek across the boundary of the right cylinder with radius 7 with bottom edge at height z = -3 and upper edge at z = 4. Note: The vectors in this field point outwards from the origin, so we would expect the flux across each face of the cylinder to be positive. Part 1 - Using a Surface Integral First we parameterize the three faces of the cylinder. Note: in the following type as theta. The bottom face: 01(r, 0) = (x₁(r, 0), yı(r,0), zı(r, 0) where 0 ≤ 0 ≤ 2T, 0 ≤ r ≤ 7 and x1 (r, 0) = y₁ (r, 0) = z1(r, 0) = y2 (r, 0) The top face: 0₂ (r, 0) = (x2(r, 0), 2(r, 0), 2(r, 0) where 0≤0 2T, 0≤r≤7 and x₂ (r, 0) = 22 (r, 0) == -3 = = 4 The lateral face: 03(0, 2) = (x3(0, 2), y3(0, 2), 23(0, 2) where 0≤0≤ 2π, -3 ≤ z ≤ 4 and x3(0) = Y3 (0) = 23(z) = Then (mind the orientation) [[F.nds - 1² [² F (01₁) · (801 -√²² J² P(0₂).
