Using Newton-Raphson method, find the real root of the function write code c++

f(x) = cos(x) x with accuracy at least 1%. Start with x0 = 0.1.

#include #include using namespace std; double f(double x) { return cos(x)-x; } double f1(double x) { return -sin(x)-1; }

int main () { double x=0.1*M_PI/180.0; double err; double tol=0.01; while (1) { err=f(x)/f1(x); x=x-err; cout<

could you tell me that where is my wrong in to my code?
