I'm trying to find a way to calculate the angular frequency of the following wave:
I know how to calculate the angular frequency for a cosine wave or sine wave by taking the coefficient of $t$, does it involve trigonometric identities? How do I go about getting the angular frequency of the sum of a cosine and a sine wave as above?
I plotted it on the graph and I could find it that way but would prefer to find it mathematically.
Any hints would be helpful.
