Question

can someone help me...i think i'm forgetting something really simple here...
integrate 1/(x^2)

Answer 1

1/(x^2) = x^(-2)

Answer 2

from there, you just use the power rule

Answer 3

which is

int(x^n dx) = (1/(n+1)) * x^(n+1) + C

Answer 4

omg...i am actually embarrassed! of course...geez...thanks jim!

Answer 5

no worries, happens to me all the time

you're welcome

Answer 6

here's a medal! haha take care!

Answer 7

oh I should mention that there's a special case

if n = -1, then it won't work because you'll have n+1 = 0 in the denominator on the right side

but it turns out that the integral of 1/x or x^(-1) is just ln(x)+C, which isn't so bad
