Hi
The problem asks to put the following expressions in z={ReA(e^i*)(e^i*)} Form
for
z=3cos(wt)-sin(wt)
z=sin(wt+pi/4)+cos(wt)
z=sin(wt)+2cos(wt-pi/3)-cos(wt)
The problem is I don't even know which parts are real and imaginary because there is no i value in any of them. I used eulers equation and expand them but arrived at a equation with only one i, two cos, and a sin. Is this the right approach or am I missing the point.
Thanks
