Bisection Method
This method is known as the method of halving the interval. This interval should include the root of the function f(x). i.e. we search about 2 points a and b such that the sign of f(a) is opposite direction of f(b) then finding c=(a+b)/2 then repeating this method until f(c) lies near zero or equal zero
Please notice that the variable should be x
begin with a=:
