You can easily get the inner angles at S,T and Q. For P, you use the parallel lines and then the above formula gives you the inner a...

If you ignore the analytic rules of what an integral should follow, but retain the algebraic rules, you can get answers for integrals that are otherwise impossible. This is called the Cauchy Principal value
