Is T supposed to be a function of X? If not, it will be treated as a constant.
If it is a function of X then you can proceed as follows. I'll make it a little more interesting and say you want to integrate 2*T + X^2. And lets say T is X^3. You can define a T by...
enter 'X^3' on the stack
enter 'T' on the stack
execute STO to store X^3 into T; you'll see the T in your softmenu now
Now if you execute INTVX in your calculus menu, it will integrate the whole thing as if you had written 2*X^3 + X^2
If you want, you can write 2*T(X) + X^2. Then proceed as follows...
enter 'T(X)=X^3' on the stack
execute DEF
Now when you execute INTVX, you'll get the same result.

Hello everyone1) I need to find the anti-derivative to the following: 6*t*X2) how to I enter the t and the X?3) How do I procede?4) Does anyone know of materials on how to do this? (not the manual, which does not help ME much).
