Let = 2xy, x + e^3z, 3^3z A.) Calculate () B.) If = 2xy, x + e^3z, 3^3z is a conservative vector field, then, find its potential function. C.) Use calculus to calculate for = 2xy, x + e^3z, 3^3z on C: the line segment from the origin to point (1, 1, 0), then, along a circular arc from point (1, 1, 0) to the point (2, 3, 1)
