Why can't i integrate this function?

So, here's my code:

syms w k c l Vi Vr p wr wi

l = (Vr-Vi)/Vi;

p = w/wr;

fw = ((k*l*Vi)/c)*(((1+p*l)*Vi)/c)^(k-1)*exp(-((1+p*l)*Vi)/c)^k ;

f1 = wi-w;

f2 = w-wi;

fr = (f1*fw);

fp = (f2*fw);

CCr = int(fr,w);

CCp = int(fp,w);

w is the only real variable. The others ( k,c,l,Vi,Vr,p,wr,wi) are constants, but i need the answer without using the values of these.

When i try to use the ''int'' it doesn't integrate and returns int(fw,w).

Thank you :)

Many functions do not have analytic (symbolic) integrals. This also applies to differential equations, so in those situations, only numeric solutions are possible.

Thanks, was stuck on this forever, i'll see what i can do. Thanks again :)

Too complicated for MATLAB to solve it.
