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^2Ɵ) (cos^2(π/2 - Ɵ)
**missing steps**
Final Equation:
Y = (X/4) sin^2(2Ɵ)
If anyone can help I'd greatly appreciate it. Thanks!
I'm trying to use the "power reducing" trig identities on this website, but I'm still not getting it...this is driving me crazy
