cos() - Mathematical Function
How is Mathematical Function "cos()" used in C++?
How to find the cosine value of an argument using c++?
Explanation
cos() is a Mathematical Function that returns the cosine Value for the given radians.
float cos( float arg );
double cos( double arg );
long double cos( long double arg );
Result :
The cosine value of 0 is :: 1
The cosine value of PI is :: -1
In the above example cos() is used to find the cosine value for "0" and the constant "PI".
Syntax to find Cosine Value:
float cos( float arg );
double cos( double arg );
long double cos( long double arg );
Example :
| #include <iostream.h> #include <cmath.h> const double PI = 3.14159265; int main() { cout << "The cosine value of 0 is :: " << cos(0) << endl; cout << "The cosine value of PI is :: " << cos(PI) << endl; return 0; } |
Result :
The cosine value of 0 is :: 1
The cosine value of PI is :: -1
In the above example cos() is used to find the cosine value for "0" and the constant "PI".
