So you are saying that I can't manipulate the following:\left( \lim_{x \rightarrow +\infty} x \right) - \left( \lim_{x \rightarrow +\infty} x \right)
into say...
\left( \lim_{x \rightarrow +\infty} x - x \right) ?
is that correct?
Suppose you have one limit
lim_{x\rightarrow \ 0}(cos(x)/x) = \infty
and a second limit
lim_{x\rightarrow \ \infty}(x) = \infty
What is the first limit subtracted by the second? Is it simply indeterminate because its inf - inf?
One...
