Evaluating Sine and Cosine at Special Acute Angles - Concept

Concept Concept (1)

If you want to make your math life incredibly easier, memorize the sine and cosine values for pi/3, pi/4, and pi/6, as well as 0, pi/2, and pi. These values constantly reappear throughout Trigonometry and pre-Calculus problems and proofs. When evaluating sine It is also useful to memorize the conversion from radians to degrees for these values; for example, to remember that pi/6 is equivalent to 30 .
