tan

tan

Tangent

Result = tan(expression)

expression

spatial, non spatial directional, scalar

Result

dimension of expression scalar

Options

--degrees or --radians

--degrees

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

--radians

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

   Expr = readmap(“Expr.map”)

   Result = tan(Expr)

   Result.map	Expr.map
