## Determine whether the planes are parallel, perpendicular, or neither (calculus & Linear Algebra)

*In the middle of the video, I was referencing infinite solutions means neither but I accidentally said parallel. I have a cut that corrects it. I use calculus techniques as well as linear algebra to solve this.

## Partial Fractions (Non-Repeating Linear Factors)

Using partial fractions to find antiderivatives. These examples all have non-repeating linear factors. This is the only type of partial fractions problem that you’ll encounter in AP Calculus BC. The video also demonstrates the cover-up method of determining the unknowns. See repeated linear factors here: http://youtu.be/O7LXxYt9G40 See quadratic factors here: http://youtu.be/A5v-3CPOkFQ

## Integrate With Partial Fraction Decomposition

Integration involving partial fraction decomposition can be a little long, especially when you have to incorporate long division of polynomials. This problem involves both long division of polynomials and partial fraction decomposition. The first thing we need to look at with this problem is the degree of the polynomial in the numerator and the degree…

## Mean value theorem | Existence theorems | AP Calculus AB | Khan Academy

The Mean Value Theorem states that if a function f is continuous on the closed interval [a,b] and differentiable on the open interval (a,b), then there exists a point c in the interval (a,b) such that f'(c) is equal to the function’s average rate of change over [a,b]. In other words, the graph has a…
