We've got an in-class essay coming up, and we've got to remember a few quotes. Any techniques that you'd like to share? I think I might speak them out a lot, or acronyms? Thanks everyone.

A is a point where the circle with equation x^2+y^2=16 cuts the X axis. Find the locus of the midpoints of all chords of this circle that contain the point A. I tried to work backwards from the answer x^2+y^2-4x but i cant seem to click on it. Any help is greatly appreciated. Thanks a truckload !

Thanks guys, really appreciate it, all the best !

i coudnt do it, appreciating everyone's help (log base 10 = log unless the base is other than that) (1). 2logx + 3 = log(x^5) -> blank on this (2). log (1+root5 / 2) + log (3+ root5 / 2) -> rationalise? All your help is always appreciated.
