WebThe inverse function is x = 4 + 2y^3 + sin ( (pi/2)y) => 0 = 2y^3 + sin ( (pi/2)y) since x=4. Therefore y=0. So the coordinate for the inverse function is (4, 0) and the non-inverse function (0, 4) So you choose evaluate the expression using inverse or non-inverse function Using f' (x) substituting x=0 yields pi/2 as the gradient.
