There are my solutions

Professor, I think you have a slight error in the solution to P1. In Eq. 1,7 you have a term $\cos(2nt)$ at the end, but should this not be a function of $x$? As you have Eq. 1.7 right now, there is no $x$dependence.

Also for solution to P2, should you have $(y+1)^2$ in the denominator of Eq. 2.8, since $(y+1)$ is our $\alpha$?

Emily, you are right (both times). Fixed

Professor, in problem 4, is equation (4.9) possibly wrong? There was no $\pi$ anywhere, same for the result equation (4.10). I think you forgot $\frac{2}{\pi}$
