x=1; using newton-raphson method tol=0.01,write a c++ program

my code is

#include #include using namespace std; double f(double x) { return n(x)+sqrt(x)-2; // this is faulty.how can I write In(x) function correctly.could you fix my code please? } double f1(double x) { return 1/x+1/2*sqrt(x); }

int main () { double x=0; double err; double tol=0.01; while (1) { err=f(x)/f1(x); x=x-err; cout In(1) + V1 -2 = 0
