Simplify: sin14°cos76 ° + cos14°sin76 ° note: sin (a + b) = sin a cos b + cos a sin b so... sin 90º = 1 one problem at a time @ß

sin14°cos76 ° + cos14°sin76 ° = sin(14 + 76) = sin 90 = 1 cos^2 32° - sin^2 32 ° = cos2*(32) = cos 64 cos 120° = cos^2 (120/2) - sin^2 (120/2) = cos^2 (60) - sin^2 (60) = (1/2)^2 - ((sqrt3)/2)^2 = 1/4 - 3/4 = -2/4 = -1/2

sin(14 + 76) = sin(90) = 1 cos(2*32) = cos(64) cos(120) = cos^2(60) - sin^2(60) = (1/4) - (3/4) = -1/2
