Homework Statement
Find the general solution for the differential equation
Homework Equations
y'' + 16y = tan(4t)
The Attempt at a Solution
I get C1cos(4t) + C2sin(4t) = 0 for my homogeneous equation.
I did the usual method of undetermined coefficients (I think I took all of the derivatives correctly). However I'm getting something strange for yp. I can't really make sense of the solution. Does this have something to do with the fact that the tangent function has discontinuities? Would this be some kind of resonance?
