Suppose the surface S is the part of the surface x = g (y, z), for points (y, z) belonging to a region R in the yz-plane. If S is oriented in the positive x-direction, what will be the formula for computing the flux of F through S? F (8 (y, z), y, z) . ( i - 8, j - 82 k) dydz O F . dA = R S F (8 (y, z) , y, z) . ( - 7 + 8, 3 + 8zk) dydz O F . d A = 1 S F . dA = |F (8 (v, z), y, z) . ( 8x 7 - 8, ] - 82 k) dydz O R S F (8 (y, z) , y, z) . ( - 8x i + 8, ) + gz k) dydz O F . dA = R S
