Derivation of Alternative Vičte Formula (digits of pi)

Hello all,

Maybe you have heard of Vičte's Formula'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.
