Hi every one, I need to find the integral of function fun= 2*pi*r0*sigma in which sigma= sigma0*exp(q*(r-r0)) the minimum limit is 0 and the maximum limit is sd= sqrt(2/(w*u*sigma)) r0=0.008 sigma0=5.813* 10^-7 w=2*pi*8*10^9 u= 8.85* 10^-12
I tried to solve it normally :D but it gives me error. does any one know how should I handle this problem? Thanks in advance

What do you mean with normally? There are thousands of methods for integrating functions. Also you should put the error message (and maybe some parts of the code) if you expect some help.
