For the formula on p44 of the tables, what are R, L and beta? Trying to figure out how I would use this formula to answer April 2015 qu 10 if I hadn't memorised anything
Yeah you'd better memorize what those terms mean and/or at least be able to derive this expression; sometimes the Yellow Book isn't as helpful as it seems at first glance. This is extracted from the ActEd notes and is a good reason (expensive as it may be) to buy them if you haven't already done so (or have relevant materials from your university).
