Description
Tan returns a Number specifying the tangent of an angle given in radians.
Arguments
  • Number value that represents an angle in radians.
  • Returns
    Number value
    Action
    Tan returns a Number specifying the tangent of an angle given in radians. It takes a right-angle triangle, and returns the length of the side opposite the specified angle divided by the length of the side adjacent to the angle.
    Examples
    Tan (1)
    Returns 1.5574 (rounded to 4 decimals). This is the tangent of 1 radian.
    Tan (45 * crPi / 180)
    Returns 1. This is the tangent of 45 degrees. Before taking the tangent, the angle is converted to radians by multiplying by crPi / 180.
