Rules for Limits
Front
1. Sum rule: The limit of the sum of two functions is the sum of their limits.
2. Difference rule: The limit of the difference of two functions is the difference of their limits.
3. Product rule: The limit of a product of two functions is the product of their limits.
4. Constant Multiple Rule: The limit of a constant times a function is the constant times the limit of the function.
5. Quotient Rule: The limit of a quotient of two functions is the quotient of their limits (as long as the limit of the denominator is not zero).

Types of continuity
Front
Functions can be continuous on an interval (it is continuous at every point of the interval) or just a continuous function (continuous at every point in the domain.

Slope of Curve at a Point
Front
The slope of the curve at the point P(a, f(a)) is the number m=lim(h-0) (f(a+h)-f(a))/h, provided the limit exists.

One-Sided Limit
Front
A one-sided limit approaches a limit from either the left or right side. Generally if it were to approach from both sides, the limit would not exist.

A two-sided limit is a limit that has the same value regardless if it is approached from the left or from the right.

Intermediate Value Theorem
Front
A function that takes on two values without taking on all the values in between.
