6.3 Trigonometric Functions of Any Angle

Find angles that are coterminal with a given angle, and find the complement and the supplement of a given angle.

Determine the six trigonometric function values for any angle in standard position when the coordinates of a point on the terminal side are given.

Find the function values for any angle whose terminal side lies on an axis.

Find the function values for an angle whose terminal side makes an angle of $30\xb0$, $45\xb0$, or $60\xb0$ with the xaxis.

Use a calculator to find function values and angles.
