Hi, I need help trying figure out this problem: I'm trying to figure out the steps to get from one equation to another
Starting Equation:
$Y = X \cos^2 \theta \cos^2 (\frac \pi 2 - \theta)$
**missing steps**
Final Equation:
$Y = \frac X 4 \sin^2 2\theta$
If anyone can help I'd greatly appreciate it. Thanks!
