SOLUTION: Expand (3cos^2theta + 2sec^2theta)^2 i figured this much but got stuck after this:
(3cos^2theta + 2sec^2theta)(3cos^2theta + 2sec^2theta)
(9cos^4theta + 4sec^2theta6cos^2thet

Question 31983: Expand (3cos^2theta + 2sec^2theta)^2 i figured this much but got stuck after this:
(3cos^2theta + 2sec^2theta)(3cos^2theta + 2sec^2theta)
(9cos^4theta + 4sec^2theta6cos^2theta + 4sec^4theta)
9cos^4theta + 4 (1/cos theta)^2 6cos^2theta + 4(1/cos theta)^4
i'm stuck, please help me! thanks!
