whats the integral for dx/x^3 ?
The integral? Do you mean the anti-derivative? Remember that \(1/x^3 = x^{-3}\) and \[ \int x^n dx = \frac{x^{n+1}}{n+1}+C,\quad n\ne-1 \]
so i'll get: x^-3 and then: \[\frac{ x ^{-2} }{ -2 } \] is that ok?
That is okay, but so is \[ \frac{x^{-2}}{-2}+1 \]as well. So you're excluding a possible anti-derivative out. That's mean you know.
Why won't you give \[ \frac{x^{-2}}{-2}-60 \]a chance either? \(-60\) has a family to feed as well.
u mean that i forgot to write aside " + c " :$
