Hello,
I have a very easy question :
$\displaystyle (2+(1/x^2))^{1/2}$
My final answer is $\displaystyle -1/x^3(2+1/x^2)^{1/2}$
But the answer sheet gives the answer of -1/2x
Am I right or wrong ??!
Thank you

Thank you for your reply.
I got it exactly like yours except that I have a -1 instead of a -2 :S
There is a step where two 2's cancel, and I get a -1 !
I just found this out from a buddy through yahoo answers : http://www.wolframalpha.com/input/?i...1%2Fx^2)^1%2F2
