三角函数积分公式大全

Answer 1

∫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 ²x dx =1/2x -1/4 sin 2x + C

∫ cos ²x dx = 1/2+1/4 sin 2x + C

∫ tan²x dx =tanx -x+ C

∫ cot ²x dx =-cot x-x+ C

∫ sec ²x dx =tanx + C

∫ csc ²x dx =-cot x+ C

∫arcsin x dx = xarcsin x+√（1-x²）+C

∫arccosx dx = xarccos x-√（1-x²）+C

∫arctan x dx = xarctan x-1/2ln（1+x²）+C

∫arc cot x dx =xarccot x+1/2ln（1+x²）+C

∫arcsec xdx =xarcsec x-ln│x+√（x²-1）│+C

∫arccsc x dx =xarccsc x+ln│x+√（x²-1）│+C
