Tangent

The tangent functions return the tangent of a numeric value that represents an angle in either degrees or radians.

Syntax:

►►─┬─ TAND ────────────┬─ (value) ────────────────────────────────────────────►◄

Invocation names:

TAND              TANR
TANDEG            TANRAD
TANGENT-DEGREES   TANGENT-RADIANS

Parameters:

(value)

Specifies the numeric value representing the angle, in degrees or radians, whose tangent is calculated.

The following rules apply to using value:

For TANGENT-DEGREES, value cannot be a value equal to the following expression, where n is any integer:
```
(n * 180) + 90
```
Thus, value cannot equal values such as -270, +270, -90, or +90 for this function.
For TANGENT-RADIANS, value cannot be a value equal to the following expression:
```
(n * X) + X/2
```
Thus, value cannot equal values such as -X/2 or +X/2 for this function.

Example:

This example calculates the tangent of 60 (in degrees):

compute 'tangent' = tand(60)

  TANGENT = 1.7321
