Today we went over the homework, started looking at continuity, and took a quiz.
We went over the multiple-choice homework, specifically problems 3, 4, and 5 on the multiple-choice homework.
3. Remember that a negative exponent will become positive when it and its base are [...]
*disclaimer: these notes are unfortunately belated due to login issues and personal computer problems. my apologies.
In class we went over the previous quiz and homework. We then focused on three main questions:
1) When do you use the trapezoidal rule?
2) What is a definite integral?
3) What exactly is the trapezoidal rule?
The trapezoidal rule is used to [...]
Blog Notes:
Review of homework:
Derivative is the instantaneous rate of change. Geometrically represents the slope of the tangent line.
Limit: (technical definition)
L is the limit of f(x) as x approaches c
If and only if
L is the number you can keep f(x) arbitrarily close to just by keeping X close enough to C, but not equal to C.
Basically, [...]
More Work With Limits:
We reviewed and answered Concepts Problems on pg. 35:
”The derivative of f(x) is equal to, which is the average rate of change and, therefore, the slope of the secant line.”
- To solve for the instantaneous rate of change (derivative) using the equation above you must:
1. find the [...]
Definition of a Limit: L is the limit of f(x) as x approaches c, if and only if, for any positive number epsilon, no matter how small, there is a positive number delta such that if x is within delta units of c (but not equal to c), then f(x) is within epsilon units of [...]
Integrals:
Trapezoids
Definition = geometric shape a total of four sides, at least two of the sides must be parallel
Find The Area of a Trapezoid:
Equation = (Trapezoid Area) http://math.about.com/library/blmeasurement.htm

Why Are Trapezoids Important?:
-One can use trapezoids to determine a fairly accurate definite integral.
(definite integral = space underneath function line or curve that [...]
