Question

5 * arctg(x) - 1/4 * arccos⁡(x) * [ (x+3 * |x-y| + x^2) / ( |x-y| * z + x^2 ) ]

C++

Answer 1

#include <iostream>

#include <cmath>

int main() {

double x = 0.1722, y = 6.33, z = 3.25 * pow(10, -4);

double s = 5 * atan(x) - 0.25 * acos(x) * ( (x + 3 * abs(x-y) + pow(x,2)) / (abs(x-y) * z + pow(x,2)) );

std::cout << s;

return 0;

}
