Question

\[\int\limits_{?}^{?}(1 + 1/x^2 +1/x^3) dx\] help pls...

Answer 1

\[\int\limits 1 + x ^{-2} ^{-3}\]

Answer 2

\[\int\limits 1 +x ^{-2} +x ^{-3}\]

Answer 3

\[x +x ^{-2+1}/(-2+1) +x ^{-3+1}/(-3+1)\]

Answer 4

x -1/x-1/2x^2

Answer 5

intergral by parts,

\[\int\limits_{}^{} 1 dx = x\]
\[\int\limits_{}^{} x^{-2} = x^{-2+1}/(-2+1) =- x^{-1}\]
\[\int\limits_{}^{} x^{-3} = x^{-3+1}/(-3+1) =- x^{-2}/2\]
