Trig identities sin a+b
Web[Since cos (π/2 − α) = sin α; and sin (π/2 − α) = cos α] Therefore: sin (α + β) = sin α cos β + cos α sin β. Replacing β with (−β), this identity becomes (because of Even and Odd Functions): sin (α − β) = sin α cos β − cos α sin … WebA is the point (cosα,sinα). B is the point (cosβ,sinβ). We draw the angle α − β in standard position and let A be the point where its terminal side cuts the unit circle. A is the point …
