You can put this solution on YOUR website!
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
