Question 1097953: If cot theta = -9/2 with theta in Quadrant II, find sin theta
Answer by Alan3354(69443) (Show Source):
You can put this solution on YOUR website! If cot theta = -9/2 with theta in Quadrant II, find sin theta
--------------
cot = x/y = -9/2
In Q2, x is negative, y is +
-----
r = sqrt(x^2+y^2) = sqrt(85)
---
sin = y/r = -2/sqrt(85) or -2sqrt(85)/85
====================
If you don't learn how this works, your life will become more difficult.
Unless you change to a psychology major, or some similar major.
