I want to integrate the following

int(vf(v), v = 0 .. infinity)

where f(v) is f(v) = 4*Pi*(m/(2*`πkT`))^(3/2)*v^2*exp(-mv^2/(2*kT))

I have tried to do the following:

(∫)[0]^(infinity)v *4 Pi*(m/(2 PikT))^(3/(2))*v^(2)*(e)^(-(mv^(2))/(2 kT))dv

But that did not give any result except this error code:

"Error, unable to parse integral, must be terminated with a differential containing DifferentialD"

Any suggestions?

Thanks in advance
