#️⃣ Basic Integration Formula

🔺∫1 dx = x + C

🔺∫ a dx = ax+ C

🔺∫ (1/x) dx = ln |x| + C

🔺∫ ex dx = ex+ C

🔺∫ sin x dx = – cos x + C

🔺∫ cos x dx = sin x + C

🔺∫ sec2x dx = tan x + C

🔺∫ csc2x dx = -cot x + C

🔺∫ sec x (tan x) dx = sec x + C

🔺∫ csc x ( cot x) dx = – csc x + C

🔺∫cosec2x.dx = -cotx + C

🔺∫secx.tanx.dx = secx + C

🔺∫cosecx.cotx.dx = -cosecx + C

🔺∫tanx.dx =log|secx| + C

🔺∫cotx.dx = log|sinx| + C

🔺 ∫secx.dx = log|secx + tanx| + C

🔺 ∫cosecx.dx = log|cosecx - cotx| + C

🔺 ∫ ax dx = (ax/ln a) + C ; a>0,  a≠1
