    Hey if anyone could give me a breakdown of how to derive the formula of a sphere using integration methods that would be brilliant :D

    All I remember is it has something to do with the centre being (0,0) but that's about it.

    Also does anyone know how to use proof by contradiction to proof that root 2 is irrational or something like that.

    Much thanks.
