Homework Statement
Simplify the expression
e^(i6theta)[ (1+e^(-i10theta))/(1+e^i2theta)]
Answer should be in terms of cosines
but i dont know how to start this problem? :S
Also, does e^(-iwt) = - coswt -jsinwt?
K so Im thinking about Eulers formula, and I get an expression with Sines and cosines not just cosines =s
