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

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)

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

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…

Complex, Hermitian, and Unitary Matrices

Complex, Hermitian, and Unitary Matrices

Remember when we talked about complex and imaginary numbers? All that a + bi stuff, it was a while ago. Well that can apply to matrices as well! We’ve been looking at real matrices thus far, but we can have imaginary or complex matrices if we have imaginary or complex terms as entries. What can…
