I am trying to solve a differential equation using NDSolve . It is of the form:
NDSolve[{y'[x]=f(x)*Integrate[g(x,t),{t,0,infinity}],y[0]=0.04},y[x],{x,0,10}]
here f is a function of x and g is a function of x and a dummy variable t for integration.
The integral cannot be solved directly in terms of x.So I tried using NIntegrate.But NIntegrate requires x to be a number while NDSolve clearly has to vary x from 0 to 10. Can anyone suggest a suitable solution to this problem?
