1) You must draw a Right Traingle.

2) Label an acute angle.

3) Label two sides so the angle has the value inside the parentheses.

For example, arccot(3) -- Label the adjacent side '3' and the opposite side '1'.

4) Use the pythagorean theorem to calculate the corresponding value of the third side.

5) The final value should be obvious.
