TURUNAN TRIGONOMETRI
y = sin x >> y' = cos x
y = cos x >> y' = -sin x
y = tan x >> y' = sec2 x
y = sec x >> y' = se x tan x
y = cosec x >> y' = -cosex cotan x
y = co tan x >> y ' = -cosec 2 x
contoh
1. y = 3 cos x + 2 sin xy' = 3 Dx(cos x) + 2 Dx (sin x)
y' = 3 (-sin x) + 2 cos x
y' = -3 sin x + 2 cos x
2. y = sin x . cos x
y' = sin x. cos x
y' = (Dx(sin x) .cos x) + (Dx(cosx) sin x)
y' = cos x . cos x + (-sin x) sin x
y' = cos2x - sin 2x
