Adding 4 tildes to format code bits. Would be nice if the author of the report would do so himself.

(assume(positive,true),assume_pos_pred:true,assume(a>0),assume(u>0,mo>0,m>0),t1:exp(-(k-y)^2-(-mo*k+m*y)^2)*exp(-u*y^2) ,t1i:ratsimp(integrate(t1,y,-inf,inf)),t2i:ratsimp(integrate(t1i,k,-inf,inf)) ,ldisp(["t1",t1,"integrate wrt",y,t1i,"over",k,t2i]))
asks: is (mo^2+1)*u+mo^2 - 2*mo*m + m^2 positive , negative or zero ?
I answer the ridiculous question and still does not do the straightforward integral.
NOw i put in two commands which i used to facilitate the simple solution but which are NOwhere used and comes back with the answer WHY ?
NOWHERE is the information tt:... NOR tti:... referred in this following
(t1:exp(-(k-y)^2-(-mo*k+m*y)^2)*exp(-u*y^2),t1i:factor(integrate(t1,y,-inf,inf)) , tt:ratsimp(diff(t1i,k)/2/k/t1i) , tti:integrate(exp(k^2*tt),k,-inf,inf) , t2i:ratsimp(integrate(t1i,k,-inf,inf)) ,ldisp(["t1",t1,"integrate wrt", y , t1i , "over", k , t2i]))

I've tried to figure out what this report is about and wasn't able to figure it out. My advice is to submit a new report which focuses on a single clear example.
