# asin¶

asin

Inverse sine

Result = asin(expression)

expression
spatial, non spatial scalar
Result
dimension of expression directional

## Options¶

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

--degrees
direction is given in degrees (default)

## Operation¶

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

## Notes¶

The values on expression must be equal to or between -1 and 1. Cells with a value outside this range will be assigned a missing value on Result. A cell with missing value on expression is assigned a missing value on Result.

## Group¶

This operation belongs to the group of Arithmetic operators

## Examples¶

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