3.1 [2 pt] Use Sympy to make two functions y = x - x grader-output + 5. You will have to use different variables for Vy the output y (in the first function) and the input y (in the second function); please use _y and y, respectively. Set the variables dy_dx and dz_dy equal to the derivative of y with respect to x and the derivative of z with respect to y, respectively. Next, use those two variables and the chain rule to define the variable dz_dx_no_sub, which is the derivative of z with respect to x. It should contain that variables x and y. To connect the notation here to the notation in the slides, _y = g(x) and z = f(y). Finally, substitute the variable_y in for the variable y in the function dz_dx_no_sub in order to define dz_dx_with_sub. It should only contain the variable x.
