Steve,
I understand you - I had similar problems long ago.
What came out is my textbook:
"Mathematical Methods in Physics and Engineering with
Mathematica",
crcpress -chapman and Hall, 2003, ISBN 1584884029
On pages 42 ff you may find the naswers;
You can use :
NDSolve[{y''[x]+y[x]==0,y[1.5]==6, y'[1.5]==20.},
y,{x,0,Pi}]
to obtain an interpolating function. To continue to work with
that result you can type:
Plot{Evaluate[y[x]/.%,{x,0,Pi}]\You may also pick up special
values, see my book. Good luck F Cap
