Integration Formulas

1 ∫ 1.dx = x + C 2 ∫ xⁿ.dx = x⁽ⁿ⁺¹⁾/(n+1) + C , (if n ≠ -1) 3 ∫ 1/x dx = log(x) + C 4 ∫ e^x dx = e^x+ C 5 ∫ sin(x) dx = -cos(x) + C 6 ∫ cos(x) dx = sin(x) + C 7 ∫ sec²(x) dx = tan(x) + C 8 ∫ cosec²(x) dx = -cot(x) + C 9 ∫ sec(x)tan(x) dx = sec(x) + C 10 ∫ cosec(x)cot(x) dx = -cosec(x) + C 11 ∫ sinh(x) dx = cosh(x) + C 12 ∫ cosh(x) dx = sinh(x) + C 13 ∫ 1/sqrt(1-x²) dx = sin⁻¹(x) + C 14 ∫ 1/(1+x²) dx = tan⁻¹(x) + C
