Ok, Thanks

It works perfect for gcl implementation
GCL (GNU Common Lisp) (2.6.1) Mon Oct 13 14:49:25 IRKST 2003

(C1) display2d:false;
(D1) FALSE
(C2) assume_pos:true;
(D2) TRUE
(C3)
(C3) defint(cos(t)^2*sin(t)/sqrt(a^2*sin(t)^2+1),t,0,%pi);
(D3) ASIN(a/SQRT(a^2+1))/a+ASIN(a/SQRT(a^2+1))/a^3-1/a^2
I observed it does not work for stable (5.9.0) maxima's cmucl implementations
as well.
