    ∫secxdx
    =∫secx(tanx+secx)dx/(tanx+secx)
    =∫(secxtanx+secx)dx/(tanx+secx)
    =∫d(secx+tanx)/(secx+tanx)
    =ln|secx+tanx|+C

      微積分常用公式:

      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
