    Is there any tips to learn geometric series formulas ? I always forget them and keep looking up online. when exams come, I tried to learn them at the time then forgot them again. also is there any good website which provides fully useful ones.
    thank you

    Why don't you derive them? That should be a good way of embedding it in your mind?

    They're given in the formula booklet which you get given a copy of in each exam! (Though of course it is good to learn them by heart as it saves time...)
    Edexcel Formula Booklet: https://qualifications.pearson.com/c...cal-Tables.pdf
    AQA Formula Booklet: http://filestore.aqa.org.uk/subjects/FORMULAE.PDF

    If you're an undergraduate then how the hell don't you know these basic formulae already? I guess you must be studying at some random "university" with no credibility.

    Maybe remember the factorisation 1-x^n = (1+x+x^2+...+x^{n-1})(1-x).
    Or just derive it fully.

    Cease and desist from defaming me immediately. I am simply stating that someone who cannot remember basic A-Level formulae ought not to be doing a mathematics or mathematics-related university course. You can disagree with that view if you wish, but do not dare to insinuate that I act with anything other than full seriousness.
