Whoops! Looks like whatever image you tried to upload didn't take. You can try uploading it again, but it might be quicker and easier just to type it out yourself using LaTeX. Using the forum's built-in parser, if you type:

[tex]\displaystyle \int_{a}^{b} \: f(x) \: dx[/tex]

It will render as:

\(\displaystyle \displaystyle \int_{a}^{b} \: f(x) \: dx\)

When you reply, please clarify. Do you really mean "pie", which is the product of "pi" and "e"? Or did you mean just the mathematical number "pi"?

Thank you!

Or is it apple or cherry? Mathlover97, the standard transliteration for the Greek letter, \(\displaystyle \pi\), is "pi". But, again, we do not know what integral you mean. Can you write it in words?
