Hi All, Another infinity question. Can someone please explain how the following expression ends up as zero please? [-(x-200) * (6000^4)/(6000+x)^4] b/w limits of infinity and 200. Apologies about the formatting. Cheers, Tom
The easiest thing to do with any of these is simply to put a large number into your calculator and see what happens. For example, if I put in 1,000,000 I get -0.001265 so I can see this is heading towards zero. The bottom line is the denominator has the bigger power and so you'll be dividing by a bigger number which will get smaller.
