This is a quick tour of the site so you can get a feel for some of the features. -- Eric Hsu
ladder
will produce a few classic ladder problems squeeze theorem limit
will produce problem pages which mention “squeeze” AND “theorem” AND “limit”. "squeeze theorem"
will produce pages with that literal phrase (and thus miss the problems tagged squeeze-theorem
) \\sec \\int rote
will find problem pages with the latex for secant, integral and the word rote
. Notice the double \\
is necessary to find a single backslash. (rocket|ladder|plane)
will find pages with “rocket” OR “ladder” OR “plane”.Tags:.*c2
finds pages with a line with “Tags” followed by anything followed by “c2”, i.e. a problem tagged c2.(rocket|ladder|plane) Tags:.*c2
This will find pages that match the first OR search AND the second Tag search.fly\b
, and that will require a word stop at the end of “fly”.View Cart

Find the following limits. Be sure to explain your reasoning at every step.
\begin{alignat*}{3}
&a) \lim_{x \to \infty}\frac{x+\sin x }{ 5x+6} & &b) \lim_
{x \to \infty}\frac{\sin x }{ x} & &c) \lim_{x \to \infty}x \sin \frac{
1 }{ x} \\
&d) \lim_{x \to \infty}\frac{x \sin x }{ x^2+5} &
&e) \lim_{x \to \infty}{\sqrt {x^2+x} - x} &
&f) \lim_{x \to \infty}\frac{x^2( 1+ \sin^2x) }{ (x+\sin x
)^2}
