Does CASIO have a website where you can download the relevant user manual .... ? (I don't suppose you have the hard copy of the manual that would have come with the calculator ....)

i have a user manual but i think it doesn't really shows how to use integrals.

I suggest you read it more carefully. I would be totally amazed if the manual for a calculator that has integration capability did not explain what buttons to press.

5. yeah it did say what to press but i don't know how to input data. the answer don't show.

6. Tell the model name ?

Tell the model name ?
$fx-991ES$

8. I think you can only do definate integral on it
See you must be able to see $\int$sign on it
press it followed by your function (comma) lower limit (comma) upper limit
ie;

$
\int{\text{(Fuction, Lower Limit, Upper Limit)}}
$

9. I already finished my short course in calculus. anyways thank for the reply I've been waiting for a reply for so long
