Check your signs on the tan and cot.

Tan is y/x and Cot is x/y.. what's wrong with it?

In what quadrants are tan and cot positive vs negative?

Explain. I learn "CAST" to help remember that but first you explain

I don't know or care what CAST is, but whatever it is you would do better to just understand the signs. What do you get if you calculate $\tan \theta = \frac{-2}{-5}$?
