Any tips on how to start this would be great. I'm aware its not geometric but the answer key indicates it diverges, however I have no idea how to physically show that with this equation. $$\sum_{n=0}^\infty\tan\frac{3\pi n}4$$ Perhaps the test for divergence is all I need to find the conclusion to this question?
