Ey"+(3+x)y'+xy=0, 0<x<1, 0<E<<1, subject to y(0)=20, y(1)=64. Find a leading approximation to the inner and outer solutions and match them.
However, I can't seem to match the two solutions, because when E tends to 0 in the inner solution, the inner solution tends to 20. While, my outer solution tends to 27e as E tends to 0.
I stretched x=Ex, and since the boundary layer is near x=0, i used y(1)=64 for the outer solution, and y(0)=20 for the inner.
Please help if anyone knows about this.
