    You can't, unless x\to\infty.

    I didn't answer your question in FMAT since I thought that it was a typo.

    Following from what special K said, I've had reason to consider very similar. Read the attachment.

    thanks for your answers.

    This integral appears in an continius distribution problem ( probability and statistics)
    , and x=30 specifically

    If you've read the attachment you'll see why integral terminals like the ones Krizalid mentions are required. Post the whole question.
