Theorem (Aitken's Acceleration): Assume that the sequence\( \{ p_n \}_{n\ge 0} \) converges linearly to the limit pand that \( p_n \ne p \) for all \( n \ge 0. Finding a solution of a differential equation can then be interpreted as finding a function unchanged by a related transformation. In addition, some nice fixed point results are obtained using this concept in the setting of MMspaces and ordered MMspaces. Because of computer hardware limitation everything including the sign of number has to be represented either by 0s or 1s. We provide some examples to back up the approach. Fixed point Iteration : The transcendental equation f (x) = 0 can be converted algebraically into the form x = g (x) and then using the iterative scheme with the recursive relation xi+1= g (xi), i = 0, 1, 2, .
