Given sin(a) = 7/25 and sin(b) = 12/13
using the sum and difference identities determine the value of
sin(a - b)
sin (a + b)=sin a cos b
cos a sin b
(you may assume angles a and b exist in the first quadrant)

example 2 – simplify: step 1: completely factor both the numerators and denominators of all fractions. step 2: change the division sign to a multiplication sign and flip (or reciprocate) the fraction after the division sign; essential you need to multiply by the reciprocal. step 3 : cancel or reduce the fractions.
