Separating real and imaginary parts
I was asked to find both sin4() and cos4() in terms of sin() and cos()
using DeMoivre's Theorem.
I couldnt figure out how to type the actual symbol for theta on here so i just used ()....
I have the Theorem in front of me and understand it (pretty much), but am struggling getting past the question above.
I need some help please! Its been driving me crazy....
