## Homework Equations

## The Attempt at a Solution

Part i)

x(t) = C1coswt + C2sinwt

dx/dt = -C1wsinwt +C2wcoswt

using IC's:

xo = C1

dxo/dt = C2w

therefore x(t) = xocoswt + (dxo/dt)/w sinwt

but for part ii I do the same thing and get A=0 and B=0. I know I'm doing something wrong here what is it?
