Multivariable Limits examples and sq. thm

  1. Jul 17, 2013 #1
    So I'm trying to study for my calc 3 exam, but I have noticed that my book doesn't have many limit questions that use sin/cos/tan, but I know those will likely be on the test. I have tried to google but I can't find many examples that have solutions. Are there any free sites that have problems to help me practice?

    Also, I can't seem to figure out when to use the squeeze theorem. In general, when do you look for it?

    Well, I can think of one REALLY good one that's open in your browser right now. :biggrin:

    I periodically stalk the forums here looking for something fun to occupy my time.

    When you recognize a function ##h## that is always greater than or equal to ##f## on an interval ##I## and a function ##g## that is always less than or equal to ##f## on the same interval, you might think about using it. The key is to get a ##g## and ##h## that have limits equal to each other at the point you want to take the limit of ##f## at in ##I##.
