asin, asinf, asinl − arc sine function
#include <math.h>
double
asin(double x);
float asinf(float x);
long double asinl(long double x);
Link with −lm.
The asin() function calculates the arc sine of x; that is the value whose sine is x. If x falls outside the range −1 to 1, asin() fails and errno is set.
The asin() function returns the arc sine in radians and the value is mathematically defined to be between −PI/2 and PI/2 (inclusive).
