Hi this isn't homework, just a practice problem I already have the answer too for my waves class:
z=sin(wt)+cos(wt)
Express this in the from Z=Re[Aej(wt+[tex]\alpha[/tex])]
I know how to express sine in the form of cosine, and cosine in the from of a complex exponential, but I don't know how to do this...I need to find the amplitude and [tex]\alpha[/tex]. Can someone help?
