Map and Table Calculation

TAN( ) function

Returns the tangent of an angle.

Syntax

TAN(Value)

Input

Value is the angle specified in radians
Domain type: any Value domain

Output

TAN returns: a real value
Domain: system domain Value

Notes:

Tip:

When the definition symbol = is used, a dependent output map or dependent output column is created; when the assignment symbol := is used, the dependency link is immediately broken after the output map/column has been calculated.

Usable in

MapCalc, TabCalc, Simple calculators

Examples

Pocket line calculator examples:

? TAN(0.7853)

returns 1.000

? TAN(DEGRAD(45))

returns 1.000

MapCalc example:

OutMap1 = TAN(InMap1)
