    I can not understand what is written here. You can arrange the brackets, etc.

    Just in case a picture helps...



    Top row is what you wrote, bottom row the derivative. Triangular network is the product rule.

    Don't integrate - balloontegrate!

    Edit: thanks for the thanks, but do refresh the page because I've just had to correct an error in the pic - sorry!
