asinf - Linux

Overview

asinf is a command-line utility that calculates the arcsine of a given value. It is commonly used in mathematical operations involving angles and trigonometric functions.

Syntax

asinf value [--radians] [--degrees]

Options/Flags

  • –radians: Output the result in radians. Default.
  • –degrees: Output the result in degrees.

Examples

Calculate the arcsine of 0.5:

asinf 0.5

Output:

0.5235987755982988

Calculate the arcsine of -0.75, output in degrees:

asinf -0.75 --degrees

Output:

-48.59002919943778

Common Issues

  • Error messages about domain errors: This usually indicates that the input value is outside the valid range (-1 to 1).
  • Incorrect output formats: Ensure that the correct output format (–radians or –degrees) is specified.

Integration

asinf can be used together with other commands for advanced calculations:

  • Combine with echo and bc for complex expressions:
echo "asinf(0.5) + pi/2" | bc

Output:

2.117993877991495

Related Commands

  • acos: Calculate the arccosine.
  • atan: Calculate the arctangent.
  • bc: Arbitrary-precision calculator.
