# tan¶

tan

Tangent

Result = tan(expression)

expression
spatial, non spatial directional, scalar
Result
dimension of expression scalar

## Options¶

--degrees
if expression is a number then the unit is degrees (default)
if expression is a number then the unit is radians

## Operation¶

For each cell, calculates the tangent of expression cell value and assigns it to Result.

## Notes¶

A cell with missing value on expression is assigned a missing value on Result.

If expression is of directional data type, a cell on expression without a direction (cell value -1) is assigned a missing value.

## Group¶

This operation belongs to the group of Arithmetic operators

## Examples¶

1. • pcrcalc
binding
Result = Result.map;
Expr = Expr.map;
initial
report Result = tan(Expr);

• python
Result = tan(Expr)
 Result.map Expr.map
