Exact trigonometric values
text:
In mathematics, the values of the trigonometric functions can be expressed approximately, as in cos ≈ 0.707, or exactly, as in cos = 2 / 2. While trigonometric tables contain many approximate values, the exact values for certain angles can be expressed by a combination of arithmetic operations and square roots. The angles with trigonometric values that are expressible in this way are exactly those that can be constructed with a compass and straight edge, and the values are called constructib
