In this paper we develop B-spline method for solving a class of Singularly Perturbed two point boundary value problems given as Ly=ϵy =F(x, y, y),xϵ(0, 1)(1) y(0) = νoy(1)=ν1,ν0,ν1ϵR(2) We use the Fitted mesh technique to generate piecewise uniform mesh, and use B-spline method which leads to a tridiagonal linear system. In case of non-linear problems we first linearize the equation using Quasilinearization technique and the resulting problem is solved by B-spline. The convergence analysis is given and the method is shown to have uniform convergence. Numerical illustrations are given in the end to demonstrate the efficiency of our method.
