求导函数变回原函数的公式

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
