Find the exact value of sin a+b

WebJul 31, 2024 · Here are the formulas: sin (a+b)=sin (a)cos (b) + sin (b)cos (a) sin (a-b)=sin (a)cos (b) - sin (b)cos (a) cos (a+b) = cos (a)cos (b) - sin (a)sin (b) cos (a-b) = cos (a)cos (b) + sin (a)sin (b) So... with your values of sin (a) = 2/3 and cos (b) = -1/5, we need to find cos (a) and sin (b). Webcos^2 x + sin^2 x = 1. sin x/cos x = tan x. You want to simplify an equation down so you can use one of the trig identities to simplify your answer even more. some other identities (you will learn later) include -. cos x/sin x = cot x. 1 + tan^2 x = sec^2 x. 1 + cot^2 x = csc^2 x. hope this helped!
