f = x^2*Exp[-2 x]*BesselI[0, 3*x];

N[Integrate[f, {x, 0, 1}]]

0.208582

NIntegrate[f, {x, 0, 1}]

0.208582

There is no way no say what is wrong without seeing what you did.

=============
Hello,

I would like to numerically integrate a particular function. I define f to be equal to that function. Then, I do N[Integrate[f,{x,0,1}]. The output is f. Why? Why don't I get an answer?

Thanks
Rohan.
