Ireally need with these questions: use basic identities to find the simplified expression- 1. (cos^2 x + sin^2 x) / (cot^2 x - csc^2 x) 2. cosine θ^2 / sine θ^2 + csc θ sin θ explanations would be greatly appreciated

Prism m and pyramid n have the same base area and the same height. cylinder p and prism q have the same height and the same base perimeter. cone z has the same base area as cylinder y, but its height is three times the height of cylinder y. the figures and have the same volume.
