    Parameters

    • x: number

      A numeric expression for which the absolute value is needed.

    Returns number

acos

  • acos(x: number): number
  • Returns the arc cosine (or inverse cosine) of a number.

    Parameters

    • x: number

      A numeric expression.

    Returns number

asin

  • asin(x: number): number
  • Returns the arcsine of a number.

    Parameters

    • x: number

      A numeric expression.

    Returns number

atan

  • atan(x: number): number
