Newton's Method

This method is known also as tangent method. we search also about 2 points such that the sign of f(x) is in opposite direction at them , to be sure that the function has a root. We use the formula:
b=a-f(a)/f'(a) where f'(a) the drevative of f(x) at x=a. we repeat this formula many time with replacing a by b until f(b) lies near the zero or equal it.
Please notice that the variable should be x
begin with a=:
f(x)=
f '(x)= the drevative of f(x)
