Hello all, Maybe you have heard of Vičte's Formula http://en.wikipedia.org/wiki/Vi%C3%A8te's_formula, which if you don't remember, has an alternative version: Expressions of this type are usually weaseled through some tricky trig identity, or by Euler's formula, which is fun. I present here a purely geometrical "derivation", if you mathematicians don't my mind my laziness as a physicist. Please see the attached PDF. AND... if you know of a place where this exact derivation is already done in detail, please show me.
