Answer:
-1
Step-by-step explanation:
The radian gives the coordinates: ( (found using the unit circle)
 (found using the unit circle)
cot=x/y
Plug the x and y coordinates into their respective places in the equation.
You get the answer of -1.
 
        
                    
             
        
        
        
<span>y= -x^2 + bc + c represents a vertical parabola that opens down.  As x approaches either + or - infinity, the function approaches  - infinity.  Imagine an upside down parabola; doing so will confirm this answer.

Whats the equation? but when ever you see f( ), what ever is in the parenthesis just plug into x
