modify this program in fortran byy adding a module (called Newton) which contains subroutine
solve. You should develop subroutine solve based on the aforementioned Newton's method.

▪ Function f(x) is x
2-1 whose zero is known. Set the input argument EPSILON to 1.E-3 and input
argument n to 1000 when you call subroutine solve and run the program

Modify the function to one that is known not to have zeros; e.g. (x
2+1)
