casinl - Linux

Overview

casinl is a command-line tool that calculates the inverse sine (arcsine) of a given real number. It is commonly used in mathematical computations and trigonometry applications.

Syntax

casinl <number>

Where:

  • <number>: The real number whose inverse sine is to be calculated.

Options/Flags

There are no options or flags available for casinl.

Examples

  • Calculate the arcsine of 0.5:
casinl 0.5

Output:

0.5235987755982988
  • Calculate the arcsine of -0.75:
casinl -0.75

Output:

-0.8410686532329146

Common Issues

  • Invalid Input: If the input number is not a real number or is outside the range [-1, 1], the result will be NaN (Not a Number).

Integration

casinl can be used in conjunction with other mathematical commands, such as cos and sin, to perform complex trigonometric calculations. For example:

angle = casinl(y / x)

Related Commands

  • acos: Calculates the inverse cosine (arccosine).
  • atan: Calculates the inverse tangent (arctangent).
  • cos: Calculates the cosine of an angle.
  • sin: Calculates the sine of an angle.
