```hi there,
im trying to solve a more involved differential equation that has a
whole family of solutions. so i started with a similar and more simple
example:

Manipulate[
Plot[Evaluate[{y[x]} /.
NDSolve[{y''[x] + y[x] == 0, y'[0] == 0, y[1] == 0}, y, x,
Method -> {"Shooting",
"StartingInitialConditions" -> {y[0] == b, y'[0] == a}}]], {x,
0, 1}, PlotRange -> All], {a, 0, 3}, {b, 0, 3}]

what i basically want is to get all the sinusoidal modes by varying
'some' parameter. i want to be able to tune one parameter so that i
get the mode with zero nods, one nod, two nods etc. how do i do that?

(i know that mathematica can solve this equation analytically, but as
mentioned above, this is just an example for a more involved
calculation.)

thanks for your help.
r.
