cos

cos

Cosine

Result = cos(expression)

expression

spatial, non spatial directional, scalar

Result

dimension of expression scalar

Options

if expression is a number: --degrees or --radians

--degrees

direction is measured in degrees (default)

--radians

direction is measured in radians

Operation

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

Notes

A cell with a 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 = cos(Expr);

   
   

   • python

   Expr = readmap(“Expr.map”)

   Result = cos(Expr)

   Result.map	Expr.map
