Next, you can find the exact value ...
The trigonometric functions of angles that are multiples of 15°, 18°, or 22.5° have simple algebraic values. These values are listed in the following table for angles from 0° to 90°. For angles outside of this range, trigonometric values can be found by applying the reflection and shift identities. In the table below, … See more In mathematics, the values of the trigonometric functions can be expressed approximately, as in $${\displaystyle \cos(\pi /4)\approx 0.707}$$, or exactly, as in $${\displaystyle \cos(\pi /4)={\sqrt {2}}/2}$$. … See more Some exact trigonometric values, such as $${\displaystyle \sin(60^{\circ })={\sqrt {3}}/2}$$, can be expressed in terms of a combination of arithmetic operations and square roots.
