Write a program to find thesquare root of a number. (Newton’s Method).

1. def func( x ):
       return x * x * x - x * x + 2
   def derivFunc( x ):
       return 3 * x * x - 2 * x
   def newtonRaphson( x ):
       h = func(x) / derivFunc(x)
       while abs(h) >= 0.0001:
           h = func(x)/derivFunc(x)
           x = x - h
       print("The value of the root is : ",  "%.4f"% x)
   x0 = -20
   newtonRaphson(x0)

Output:-
