Find all critical points and their classifications

Reference no: EM131015337

Let f(x, y) = 1 + 3x² - cos (2y).

Find all critical points & their classifications them as local maxima, local minima, saddle point, or none of these? So far I've gotten one critical point and classification purely from guessing, and have no work to show.
