Pseudocode for Bisection Method

1. Start

2. Define function f(x)

3. Input 
	a. Lower and Upper guesses x0 and x1
	b. tolerable error e
4. If f(x0)*f(x1) > 0
	print "Incorrect initial guesses"
   	goto 3
   End If

5. Do 
	x2 = (x0+x1)/2
	If f(x0)*f(x2) < 0
		x1 = x2
		x0 = x2
	End If
   while abs(f(x2) > e
6. Print root as x2

7. Stop
