What is the limit?
Anyone know how to evaluate this limit?
(10,000 / (x+10,000))^2 Y = divided by (x goes to infinity) (20,000 / (20,000 +x^2) The answer is 10,000^2 / 20,000. I don't get that answer. The solution did not show method. Switching terms around I have [10,000^2/20,000] * [(x+10,000)^2 /(20,000 + x^2)]. If the right side was 0/0 i would take the derivative of numerator and denominator and try again but I don't think that works for infinity divided by infinity. Anyone out there know why the right side end up being one?

Thanks for responses. I did not realize that both were indeterminate forms and forgot that the highest term in numerator and denominator dominate for limits.
