Limits

Some students have asked if there was online material that they could read or study.

Limits: This follows my explanation of a limit closely. Read examples 1 and 2.
Left and right handed limits: Read examples 1 and 3. Practice problems here with solutions. Remember that the left-handed limit is the limit as $x$ approaches the value $a$ from the left-hand side; $\displaystyle\lim_{x \to a^{-}}f(x)$ . We use the $-$ symbol to denote the left-hand side. The right-handed limit is the limit of $f(x)$ as $x$ approaches the value $a$ from the right-hand side; $\displaystyle\lim_{x \to a^+} f(x)$ . We use the $+$ symbol to denote the right-hand side.
Limit properties: Read examples 1 and 2.
Computing Limits: More practice problems with solutions.
Continuity: Read examples 1 and 2. Practice problems here with solutions (try problems 1 and 2).
