Hi, I'm having problem to get the integral computed below (q3):
syms teta h t z n;
f=exp((-n^2*pi^2*t)/h^2)*cos(0.8*n*pi)*cos(n*pi)*(1/2-z/h);
f1=symsum(f,n,-8,8);
q=exp(-(tan (teta)^2-(z+03*h)^2)/4*t)*(1+2*f1);
q1=int(q,z,-h/2,h/2);
q3=int((exp (-1/4*t)/t)*q1,t,1,10)
q2=(1/(2*h))*q3;
I'm getting the following note:
Warning: Explicit integral could not be found.
Could someone help me?

Thanks Walter, I guess we have...
But I'm getting the first integral (q1). I believe that my big problem is to get "q3". Since the integral of "exp ((-1/4*t)/t)..." will lead me to the Exponential Integral function.
I'm not finding a way to solve this, nor seeing my mistake...
