PROBLEM
Solve the initial value problem (we discuss how to do this, but did not yet do this in class)
x¨ + ω2x = sin(ωt), x(0) = x˙(0) = 0
First step: find a solution to the non-homogeneous equation.
PROBLEM
Find a solution of non-homogeneous equation
x¨ + ω2x = cos2(ωt)
Hint: use previous lecture material and homework to represent cosine-squired as a sum of trigonometric functions.
