This set goes over all those pesky theorems, rules, and properties that are useful to know when it comes to the AP test.

### When does the limit not exist?

1. f(x) approaches a different number from the right as it does from the left as x→c

2. f(x) increases or decreases without bound as x→c

3. f(x) oscillates between two fixed values as x→c

### Intermediate Value Theorem

If f is continuous on the closed interval [a,b] and k is any number between f(a) and f(b) then there is at least one number c in [a, b] such that f(c) = k

### Extrema Value Theorem

If f is continuous on the closed interval [a, b], then f has both a maximum and a minimum on the interval.

### The first derivative gives what?

1. critical points

2. relative extrema

3. increasing and decreasing intervals

### Rolle's Theorem

Let f be continuous on the closed interval [a, b] and differentiable on the open interval (a, b). If f(a) = f(b) then there is at least one number c in (a, b) such that f'(c)= 0

### Second Fundamental Theorem of Calculus

If f is continuous on an open interval containing a, then for every x in the interval the derivative of the the integral of f(x) dx on said interval is equal to f(x)
