Question: 1.) Consider the function: f(x, y) = cot '(1 + x) - 2ex+3y If x = $2 - t2 and y = 3t+ tan(1-s), use

1.) Consider the function: f(x, y) = cot '(1 + x)

1.) Consider the function: f(x, y) = cot '(1 + x) - 2ex+3y If x = $2 - t2 and y = 3t+ tan(1-s), use the multivariate chain rule to evaluate - when s = 1 and t = -1. 2.) Suppose z is a differentiable function of x and y implicitly defined by the equation: Z3 - yiz = x2 + 7 - sin(x-1) log2 x Evaluate when (x,y,z) = (1,0,2)
