): find cot b and sin b of an angke whose equation of its terminal side is 5x + 2y = 0 where x>0
---
Let x = 2, then y = -5
Let x = 0, then y = 0
-----
The terminal side passes thru (2,-5)
---
Since x = 2 and y = -5,
r = sqrt[2^2 + 5^2] = sqrt[29]
---
cot = x/r = 2/sqrt(29)
---
sin = y/r = -5/sqrt(29)
