Dx sin x=cos x
cos x = -sin x
tan x = sec2 x
cot x = -csc2 x
sec x = sec x tan x
csc x = -csc x cot x sin x dx = -cos x + C
cos x dx = sin x + C
tan x dx = ln |sec x | + C
cot x dx = ln |sin x | + C
sec x dx = ln |sec x + tan x | + C
csc x dx = ln |csc x – cot x | + C sin-1(-x) = -sin-1 x
cos-1(-x) = - cos-1 x
tan-1(-x) = -tan-1 x
cot-1(-x) = - cot-1 x

v = udv + v
v = uv = udv + v
udv = uv - v
cos2θ-sin2θ=cos2θ

sech-1 x dx = x sech-1 x- sin-1 x + C
csch-1 x dx = x csch-1 x+ sinh-1 x + C
sin 3θ=3sinθ-4sin3θ
cos3θ=4cos3θ-3cosθ
→sin3θ= (3sinθ-sin3θ)
→cos3θ=?(3cosθ+cos3θ)
sin x = cos x =
sinh x = cosh x =
正弦定理:= = =2R
余弦定理:a2=b2+c2-2bc cosα
b2=a2+c2-2ac cosβ
c2=a2+b2-2ab cosγ
sin (α±β)=sin α cos β ± cos α sin β
cos (α±β)=cos α cos β sin α sin β
2 sin α cos β = sin (α+β) + sin (α-β)
2 cos α sin β = sin (α+β) - sin (α-β)
2 cos α cos β = cos (α-β) + cos (α+β)
2 sin α sin β = cos (α-β) - cos (α+β) sin α + sin β = 2 sin (α+β) cos (α-β)
sin α - sin β = 2 cos (α+β) sin (α-β)
cos α + cos β = 2 cos (α+β) cos (α-β)
cos α - cos β = -2 sin (α+β) sin (α-β)
tan (α±β)= ,cot (α±β)=
