for example, I define a function f like this and I want to NIntegrate it:
f[x_,y_,z_]:=Sin[x+y+z]
If I do like this:
NIntegrate[f[x,y,z],{x,0,1},{y,0,1},{z,0,1}]
it runs all right and get the correct answer.
but if I do like this:
g[z_]:=NIntegrate[f[x,y,z],{x,0,1},{y,0,1}]
NIntegrate[g[z], {z, 0, 1}]
I can also get correct answer but there exists an error:
"NIntegrate::inum:
Integrand f[x,y,z] is not numerical at {x,y}={0.5,0.5}.More..."
how can I avoid this error??
