atanl - Linux
Overview
atanl is a command-line utility that calculates the arctangent of a number. It is commonly used in trigonometry and geometry applications, as well as in programming and mathematics.
Syntax
atanl(x, y)
- x: The numerator of the arctangent calculation.
- y: The denominator of the arctangent calculation.
Options/Flags
This command does not support any options or flags.
Examples
# Calculate the arctangent of 3
atanl(3, 0)
# Calculate the angle between two points (1, 2) and (4, 6)
atanl(6 - 2, 4 - 1)
Common Issues
- Division By Zero Error: If the denominator is zero,
atanl
will return an error. Ensure that the denominator is always non-zero.
Integration
atanl can be integrated with other Linux commands to perform more complex calculations. For example:
# Calculate the angle of inclination of a line using bc
echo "scale=4; a(10, 1)" | bc -l
