assumptions in integrals' computation in programming mode
Good morning, if I want to calculate the following integral:
int((tx)^(1/2)*ln(x),x,0,t) it is necessary to make the following assumptions: assumes(t>0); additionally(t>x). My question is the following: how can I assign an assumption to a variable in #cas ... #end programming mode? See attachments Thanks a lot, Roberto (robmio)

For example, in this "#cas ... #end" program: #cas cavolo():= BEGIN LOCAL fnz, Fnz; fnz:=(x)>(tx)^(1/2)*LN(x); Fnz:=(t)>int(fnz(x),x,0,t); RETURN Fnz(t); END; #end in which zone do I put "assume(...)"? Putting the "assume()" statement between the "fnz" statement and the "Fnz" statement, I get nothing. Thanks a lot, robmio
