Homework Statement
Is there a way to simplify the following expression?
##[cos(\frac {n \pi} 2) - j sin(\frac {n \pi} 2)] + [cos(\frac {3n \pi} 2) - j sin(\frac {3n \pi} 2)]##
Homework Equations
##e^{jx} = cos(x) + j sin(x)##
The Attempt at a Solution
##cos(\frac {n \pi} 2)## and ##cos(\frac {3n \pi} 2)## produce the same result for all values of ##n##
Likewise, ##- j sin(\frac {n \pi} 2)## and ##- j sin(\frac {3n \pi} 2)## produce the same result for all values of ##n##
