The syntax for the acos function in the C Language is: double acos(double x); Parameters or Arguments x A value between -1 and 1. A domain error will occur ifxis not between -1 and 1. Returns The acos function returns the arc cosine of a number represented byx. It will return a ...
acos() function is a library function of cmath header, it is used to find the principal value of the arc cosine of the given number, it accepts a number (x) and returns the principal value of the arc cosine of x in radians.

Y= acos(X)returns theInverse Cosine(cos-1) of the elements ofXin radians. The function accepts both real and complex inputs. For real values ofXin the interval [-1, 1],acos(X)returns values in the interval [0, π]. For real values ofXoutside the interval [-1,1] and for complex...
Return Value Theacosfunction returns the arccosine of x in the range 0 to π radians. Remarks This program prompts for a value in the range -1 to 1. Input values outside this range will produce _DOMAIN error messages. If a valid value is entered, the program prints the arcsine and ...
The acos function returns the arccosine of x in the range 0 to π radians. If x is less than –1 or greater than 1, acos returns an indefinite (same as a quiet NaN). You can modify error handling with the _matherr routine....
The acos function fully supports tall arrays. For more information, see Tall Arrays. C/C++ Code Generation Generate C and C++ code using MATLAB® Coder™. Usage notes and limitations: Generates an error during simulation and returns NaN in generated code when the input value X is real, bu...
