Back # Math.SQRT1 2

The ** Math.SQRT1_2** property represents the square root of 1/2 which is approximately 0.707:

$$\backslash mathtt\{\backslash mi\{Math.SQRT1\_2\; =\; \backslash sqrt\{\backslash frac\{1\}\{2\; =\; \backslash frac\{1\}\{\backslash sqrt\{2\; \backslash approx\; 0.707$$

Because `SQRT1_2`

is a static property of `Math`

, you always use it as `Math.SQRT1_2`

, rather than as a property of a `Math`

object you created (`Math`

is not a constructor).

`Math.SQRT1_2`

The following function returns 1 over the square root of 2:

function getRoot1_2() { return Math.SQRT1_2; } getRoot1_2(); // 0.7071067811865476
