+   * Calculate the sine of a value.

+   * To avoid confusion with the matrix sine, this function does not apply
+   * to matrices.
+   *
+   * Syntax:
+   *
+   *    math.sin(x)
+   *
+   * Examples:
+   *
+   *    math.sin(2)                      // returns number 0.9092974268256813
+   *    math.sin(math.pi / 4)            // returns number 0.7071067811865475
+   *    math.sin(math.unit(90, 'deg'))   // returns number 1
+   *    math.sin(math.unit(30, 'deg'))   // returns number 0.5
+   *
+   *    const angle = 0.2
+   *    math.pow(math.sin(angle), 2) + math.pow(math.cos(angle), 2) // returns number ~1
+   *
+   * See also:
+   *
+   *    cos, tan
+   *
+   * @param {number | BigNumber | Complex | Unit} x  Function input
+   * @return {number | BigNumber | Complex} Sine of x
