SP#5: Unit J Concept 6 - Partial Fraction Decomposition with Repeated Factors



When decomposing these problems, make sure you count up the powers. If there is an (x-2)^2, make sure you give one factor and (x-2) denominator then the one next to it should have an (x-2)^2 denominator. Also, When you check your answer on a calculator, it should be in Row-Echelon Form. The numerators of the decomposed answer comes directly from what the calculator reads.

Be sure to combine your like terms correctly. Don't forget the A, B, or C in front of each variable. Also, make sure you distribute the common denominator to the top as well. Without it, your like terms will be completely wrong.

SV#5 Unit J Concept 3-4 - Solving for Matrices

Click HERE to watch my video.

Solving for matrices can be super tricky! Just make sure not to confuse your z's with a 2. That tends to throw many people off. Also, make sure your elementary row operations are correct. This is the easiest part of solving for matrices, but one little mistake will ruin your entire answer.

SV#4: Unit I Concept 2 - Graphing Logarithmic Functions and Identifying Key Parts

To watch my video, click HERE.

In this video, you should be aware of the order that I solved my key parts in.  I skipped key points because I felt like it would be more relevant once I start graphing the equation.  Also, make sure that you plug in the zeros into the correct number for finding x and y intercepts.  Remember that finding x-intercepts require you to plug in zero to the variable "y." For y-intercepts, you plug the zero into the variable "x."


P.S. I apologize for sounding like a dying cat. I had to pause the video a few times to clear my throat.  Sorry if the abrupt changes in volumes and tones scared you.
