Question 235020
Let A be the angle.


If sin(A) = -.5, this means the angle is -30 degrees.


You just plug -.5 into your calculator and solve for the angle.


You then use your calculator to find cot (-30).


cot (-30) = -1.732050808


If your calculator doesn't have a cot function, get the tan and divide that into 1 to get the cot because cot = 1/tan
