You also need to be able to go backward and know what angle has a sine of ½ or a tangent of −√ 3 . While it’s easy to work them out as you go (using easy right triangles), you really need to memorize them because ...
WebThe circle is marked and labeled in both radians and degrees at all quadrantal angles and angles that have reference angles of 30°, 45°, and 60°. At each angle, the coordinates are given. These coordinates can be used to find the six trigonometric values/ratios. The x-coordinate is the value of cosine at the given angle and the y-coordinate ...

WebNow, identities that involve two angles, such as α and β, will be introduced. The first is the difference identity for cosine. Difference Identities for the Cos Function cos (a – b) = cos a cos b + sin a sin b. To prove this identity, place angles α (alpha) and β (beta) in standard position, as shown in the figure at the right.
