Please answer f, g and h

Consider the the dx2y2 orbital, which has the angular form (ignoring normalization constants) dx2y2=sin2cos2 f. In what direction(s) is it most probable to find the dx2y2 electron? Explain. g. Sketch the surface density function r2R2 for 6dx2y2 orbital. Your drawing should include all essential qualitative features, e.g., phases, nodes, extrema, and reference axes. h. Is the dx2y2 orbital orthogonal to the angular orbital shown at right? Explain your reasoning. For this problem, assume maximum symmetry in the xz coordinate plane consistent with the diagram shown; assume also that the lobes lie on the xz coordinate plane and are symmetric above and below that plane.)
