Thanks to everyone who replied. I guess I was too hasty in stating my concern and should have been less vague. The textbook solution that I saw stated that the Euler identity could be used to remove the two terms in e with complex exponents to be replaced with a 2cos(wt+p) term (p being the...
Hey, I have a simple question to ask. Some sources I have seen develop the solution for the underdamped case with an exponential term multiplied by a Cosine term. This is due to the application of the Euler identity to the solution with two exponentials each with one of the complex conjugate...
