ccosf - Linux
Overview
ccosf calculates and prints the cosine of an input angle specified in radians. It is primarily used in mathematical computations, trigonometry, and geometry.
Syntax
ccosf <angle in radians>
Options/Flags
None
Examples
- Calculate the cosine of an angle of 45 degrees (π/4 radians):
ccosf(M_PI/4)
Output:
0.707107
- Find the cosine of an angle given in degrees:
ccosf(30 * (M_PI / 180))
Output:
0.866025
Common Issues
- Incorrect angle: Ensure that the input angle is specified in radians. If degrees are provided, convert them to radians using
angle * (M_PI / 180)
. - Overflow and underflow: For extremely large or small angle values, the result may be inaccurate or result in overflows/underflows. Consider limiting the range of input angles or using alternative methods for more precise results.
Integration
- With
