I need help with these kind of problems!

Can someone tell me how to work this problem out?

Given tan0=2 square root of 5 over 4, and sin0<0.

a. cos0 b. csc0

The 0 after tan, sin, cos, and csc stands for angle. The 0 after the < stands for negative or less than. I know it sounds confusing, but if somebody knows a great web site to get help from, please inform me!
