How to solve lim x approaches infinity (Inx-e^x)?? anybody can help me??

Question

irishboy123 · Answer

$ \lim\limits_{x \to \infty} \ln x-e^x$     ?????

if this is it, the exponential is the dominant term so you can see where the overall function is going

....South

Formalism:
$=  \lim\limits_{x \to \infty} \ln x- \lim\limits_{x \to \infty} e^x$  

so its like a big number minus a mahoosive number

So do we have to diffirentiate the fuction??

irishboy123 · Answer

i don't see the point of differentiating, no

i reckon stuffing some numbers into your calculator would get you there.  let x = 1, 10, 100 should do it.....
