The acos () function defined in the math.h header file. It helps to return the arc cosine value of the given number in radians. The arc cosine means inverse cosine value. double acos (double x); #where x can be in int, float or long double.
Function prototype of C math library function acos () double acos( double n ); where, n = floating point value between 1 and -1 (1 >= n >= -1). This function returns the arc cosine of n in radians that range between 0 and pi [0, pi].
23 lip 2024 · c o s − 1 (x) \mathrm {cos}^ {-1} (x) cos−1(x) \mathrm {arccos} (x) arccos(x) is the most commonly used notation, as \cos^ {-1} (x) cos−1(x) may be misleading – remember that inverse cosine is not the same as the reciprocal of the function (in other words, raising to the power -1 −1):
The C library acos () function returns the arc cosine of x in radians. This parameter must be in the range of -1 to 1 and if the given input set to out of range, it will return nan and may errno to EDOM. Syntax. Following is the C library syntax of the acos () function −. double acos (double x) Parameters.
