comment How to Solve or LinearSolve $A = I$ matrix equation?
The question related to finding the left inverse of some matrix $A$. But a solution I found from my linear algebra course is to use Gaussian elim. (RowReduce) with the augmented matrix $[A I]$.

comment Need help evaluating definite integral to a function of Y
Yes, it is independent of $u$. That's a good point, I will just need to make sure it would be valid for this problem, and should have included that $Y = \sqrt{2T}\cos(U)$, and will do so now.

but note that it's up to you to know that the replacement is equivalent.
