Question

anti-derivative (1)/x^2dx

Answer 1

\[\int x^{-2}\ dx\]

Answer 2

to derive a power we multiply and subtract 1, to undo that we add 1 and divide

Answer 3

So would my answer be (-1/3x^3)?

Answer 4

it would; +C

Answer 5

opps, read it wrong: -1/3 x^-3

Answer 6

+C ....

Answer 7

\[\int x^{-2}\ dx=-\frac{1}{1}x^{-1}=-\frac{1}{x}+C\]
thats better

Answer 8

okay thanks. I need to know how to type another problem but I do not know how to type it in integral notation. COuld you explain how to do that please?

Answer 9

I gotta get to class at the moment; but good luck :)

Answer 10

ok well later Thanks. :)

Answer 11

use the power rule backwards

Answer 12

\[\frac{d}{dx}x^n=nx^{n-1}\]
\[\int x^n dx=\frac{x^{n+1}}{n+1}\]
