The problem is in the picture. #17
I would have typed it but there are graphs that are needed for solving it. Basically trying to figure out which y(t) graph belongs to one of the sinusoidal forced equations with various parameters.
euler's formula eit=cost +isint
polar form of complex numbers
The Attempt at a Solution
so I have been complexifying the right hand side, using the guess and check method with a substituted αewit. Once I find α I convert it into its polar form and then change y particular so I can see it's amplitude. This along with 2π/w for the period. Am I going about this the wrong way?
