20 Des 2015 tan x = sin x / cos x jadi sin x kali cos x/ tan x = sin x kali cos x / sinx/cosx = cos²x. kvargli6h dan 48 orang menganggap jawaban ini membantu.

Deriving the differential of cos θ from first principles The graphs of sinx, cosx and tanx Sine • The maximum value of sinx is 1. At x = 90°, sinx = 1. • The minimum value of sinx is −1. At x = 270°, sinx = −1. • The graph of sinx crosses the x-axis three times in the interval 0° ≤ x ≤ 360°. At x = 0°, 180°, and 360°, sinx = 0.

tan x = opp/ adj (1) sin x = opp/ hyp (2) cos x = adj/ hyp (3) From equation (2), we rearrange so that. opp = hyp * sin x. From equation (3) we rearrange so that. adj = hyp * cos x. Substitute these values into equation (1) tan x = (hyp * sin x) / (hyp * cos x) Cancel out the common hyp term, and you have. tan x = sin x / cos x

sin(x + y) = sin x cos y + cos x sin y cos(x + y) = cos x cos y – sin xsin y tan x + tany tan(x + y) = 15 tan x tan y sin 2x = 2 sin x cos x cos2x = cos? x - sin? x = 2 cos?
