Also I am trying to find the tan of 150 degrees
so I have to dive (1/2)/(- square root 3/2) can anyone also show me how to do this.
if cot(-180 degrees)
would you add 360 to get positive 180
then do cot (180) to get 1/0 or undefined
my second problem is if tan= 1.3
what is the value of (cot-angle)
I am not sure how to do this.
Can anyone help me please?
as a counterclockwise rotation of
hence the cotangent of that angle is undefined.
For cotangent, you only need know that it is the reciprocal of tangent.
In the unit-circle,
