That means that you do not need a calculator to find these values. This knowledge should let you bound or estimate the values at other angles. 4. Sketch the angle. Evaluate the function at the given angle without a calculator. (e.g. cos 90o = 0) cos sin tan . tan cos sin. sin 135o tan 300o cos 180o. III.
