Hello,
I'm tring to solve a diffrential equation with
its upper boundary as a variable.
and then I want to integrate it, and define
it as a funcion with two variable.
However, I don't know why it doesn't work at the second step.
my equation is as following,
f[c_?NumberQ]:=y[x]/.NDSolve[{eqn,y[0]==1,y'[0]==0},y,{x,0,c},MaxSteps-
>10000][[1]]
n[w_NumberQ,c_NumberQ]:=NIntegrate[c*y[x]*(r-w)],{r,w,1}]
function f works well, however there's some problem in funcion n,
and it's confused me for a long time...,
thanks for your help!!
Best Regards!!
Lynn
