Question 235105
Given that sin0=-1/2 and 0 lies quadrant lV,find the following value, cot0
----------
You can do this on a calculator:
arcsin(-1/2) = -30
cot(-30) = -sqrt(3)
-------------------
If you have to do without a calculator:
sin = -1/2
cos = sqrt(1 - sin^2) = +/- sqrt(3)/2
cot = cos/sin = -sqrt(3)
