Hi Could someone please help with this integration:

`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,n);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;Warning: Explicit integral could not be found.`

q3 =

int((pi^(1/2)*(erf((5*h*(-t)^(1/2))/4) – erf(7/4*h*(-t)^(1/2)))*(exp((2778046668940015*n^2*t)/(281474976710656*h^2)) + cos(pi*n)*cos((4*pi*n)/5) + 2*n*cos(pi*n)*cos((4*pi*n)/5)))/((-t)^(3/2)*exp(t/4)*exp((t*tan(teta)^2)/4)*exp((2778046668940015*n^2*t)/(281474976710656*h^2))), t = 1..10)
