The
acos() function is defined in
valarray header file. This function is used to calculate arc cosine of the value of each element in valarray and returns a valarray containing the arc cosine of all the elements.
Syntax:
acos(varr);
Parameter: This function takes a mandatory parameter
varr which represents valarray.
Returns: This function returns a valarray containing the arc cosine of all the elements.
Below programs illustrate the above function:
