4. x* · y f(x, y) (x, y) # (0,0); x4 + y2 f (0,0) = 0, (x, y) = (0,0). Calculate a formula for the partial derivative valid at every (x, y) # (0,0). af

Q: Given F(r, s, t) = -r(58³ + 7tº), compute: Frst

A: Frst is a third order partial, where we differentiate first with respect to r, then with respect to…
