It may have been common to pronounce $f'$ as 'f dash' in British English in 1981, but for as long as I've been learning mathematics (including eight years in a British university) I've always called it 'f prime'.

Jun 23 answered Formula for gallons in a trough Jun 23 comment $\int \cos^2 x$ - Where did I go wrong? @Aryabhata that's a nice trick, though I think for pedagogical purposes I prefer yunone's answer (+1 to both, though) Jun 22 comment How can I prove that functions in a certain family have unique maxima? If you can give more detail on the class of functions (e.g. an explicit parameterization, or a set of criteria which all functions in the class satisfy) then we will be able to give you a better answer. Jun 22 revised Volume of a cissoid? latex Jun 22 comment Best way of computing the decimal representation of a fraction with an arbitrary precision? @Theo: when you say 'compute it until the digits start repeating' what do you mean? For example, when does your algorithm decide that the digits start repeating when computing the decimal expansion of 121212129/999999999? Jun 22 comment How can I count waypoints between a curve? What form does the curve between A and B take? Is it a straight line, an arc of a circle, a cubic spline (the last two will require additional 'control points' to be specified - what are they?) or something else?
