so i made the e^i\pi/4 into cos(\pi/4)+sin(\pi/4) by using eulers formula. Now i calculated the complex amplitude to be √2.414. and the complex angle to be 35.26 degrees or 0.6155 rad. The answer i get is x = Re [√2.414 e^i0.6155t e^iwt ] is this correct?

Homework Statement For my waves class, I have to do this problem. I've previously completed a question like this except there was no phase constant (∏/4) in that question. Express the following in the form x = Re [Ae^i\alphae^iwt x=cos(wt + ∏/4) - sin(wt) Homework Equations euler's...
