Continuity and Limits (Section 1.4; 9, 13, 18, 20, 25)

 A function can be continuous at a point, and interval or everywhere.  We can tell if three things are required!

Using a Theorem to find a limit (1.3 #74)

 We can use Theorems together with algebra tricks to find limits that have the indeterminate 0/0 form.

The conjugate comes to the rescue again! (1.3 #75)

To find the limit, we turn to the conjugate once more!

Limits that go to 0/0 (1.3 #53)

Don't fear the "∆x" it works like a single variable, and refers to the change in x.

More Algebra Tricks: The Conjugate (1.3 #52)

 Her we take advantage of (a+b)(a-b) = a² - b ².

to resolve an indeterminate form.

Using Algebra Tricks to Find a Limit (1.3 #51)

 If you substitute 4 for x, we get a 0/0 situation we call an indeterminate form which can resolved with some algebra tricks.
