Your work can be viewed below, but no changes can be made. 1. [SCalcCC2 11.5.06.] 4/4 points Use the Chain Rule to find z / s and z / t . z = x / y , x = se t , y = 1 + se - t z / s = (1/(1+s*exp(-t))(exp(t))-((s*exp(t))/(1+s*exp(-t))^2)(exp(-t))) exp(t) / (1 + s exp(-t)) ^ 2 z / t = (1/(1+s*exp(-t))(s*exp(t))-((s*exp(t))/(1+s*exp(-t))^2)(-s*exp(-t))) (2 s^2 + s exp(t)) / (1 + s exp(-t)) ^ 2 2. [SCalcCC2 11.5.10.] 4/4 points Let W ( s , t ) = F ( u ( s , t ), v ( s , t )), where u (1, 0) = 2, u s (1, 0) = -2, u t (1, 0) = 6, v (1, 0) = 3, v s (1, 0) = 5, v t (1, 0) = 4, F u (2, 3) = -1, and F v (2, 3) = 10. Find the following.
