【答案】 微积分公式
  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
  sec-1(-x) = - sec-1 x
  csc-1(-x) = - csc-1 x
  Dx sin-1 ()=
  cos-1 ()=
  tan-1 ()=
  cot-1 ()=
  sec-1 ()=
  csc-1 (x/a)=
  sin-1 x dx = x sin-1 x++C
  cos-1 x dx = x cos-1 x-+C
  tan-1 x dx = x tan-1 x- ln (1+x2)+C
  cot-1 x dx = x cot-1 x+ ln (1+x2)+C
  sec-1 x dx = x sec-1 x- ln |x+|+C
  csc-1 x dx = x csc-1 x+ ln |x+|+C
  sinh-1 ()= ln (x+) xR
  cosh-1 ()=ln (x+) x≥1
  tanh-1 ()=ln () |x| 1
  sech-1()=ln(+)0≤x≤1
  csch-1 ()=ln(+) |x| >0
  Dx sinh x = cosh x
  cosh x = sinh x
  tanh x = sech2 x
  coth x = -csch2 x
  sech x = -sech x tanh x
  csch x = -csch x coth x
  sinh x dx = cosh x + C
  cosh x dx = sinh x + C
  tanh x dx = ln | cosh x |+ C
  coth x dx = ln | sinh x | + C
  sech x dx = -2tan-1 (e-x) + C
  csch x dx = 2 ln || + C
  duv = udv + vdu
  duv = uv = udv + vdu
  → udv = uv - vdu
  cos2θ-sin2θ=cos2θ
  cos2θ+ sin2θ=1
  cosh2θ-sinh2θ=1
  cosh2θ+sinh2θ=cosh2θ
  Dx sinh-1()=
  cosh-1()=
  tanh-1()=
  coth-1()=
  sech-1()=
  csch-1(x/a)=
  sinh-1 x dx = x sinh-1 x-+ C
  cosh-1 x dx = x cosh-1 x-+ C
  tanh-1 x dx = x tanh-1 x+ ln | 1-x2|+ C
  coth-1 x dx = x coth-1 x- ln | 1-x2|+ C
  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)=
  ex=1+x+++…++ …
  sin x = x-+-+…++ …
  cos x = 1-+-+++
  ln (1+x) = x-+-+++
  tan-1 x = x-+-+++
  (1+x)r =1+rx+x2+x3+ -1= n
  = n (n+1)
  = n (n+1)(2n+1)
  = [ n (n+1)]2
  Γ(x) = x-1e-t dt = 22x-1dt = x-1 dt
