In decimal approximations, use 4 decimal places. 1. a. Use Ptolemy's Theorem and the quadrilateral at right to get an expression for chords that involves the chord of the difference of two angles. (Like we did sums). b. Rewrite part a in terms of sines to get the sine difference formula sin(01-02)=sin 01 cos 02 - cos 01 sin 02 A Note that 01 and 02 are just dummy variables, so use any variables you wish in your formula.
