i know this isn't exactly homework, but i couldn't find anywhere else to put it! we've been doing s.h.m. in physics, and when we considered a simple pendulum my teacher mentioned that you can also have a conical pendulum, but the maths for it is more complicated. i want to know more about this - is it something i could understand with A level maths? (differential equations, vectors, integration by parts, by substitution, inverse trig, functions, basic mechanics) i'm not adverse to learning new maths - i have a whole six weeks of holiday to come. what does anyone think?
