SP #5: Unit J Concept 6 - Partial Fraction Decomposition with repeated factors



The reader must be careful when doing this problem because there are four equation. Also, make sure you do your math correctly or one incorrect variable can mess up your whole system. Also, make sure that you multiply the numerators and combine like terms correctly. Check your work!

SP #4 - Partial Fraction Decomposition with distinct factors



This part is called composing. We combine the fractions into a larger fraction. We then combine like terms. 
This part is called decomposition. We are given a large fraction and are trying to find the small fractions that multiplied to make it. 
Simply type the left part into the calculator and using rref you will get the answer on the right, which is your A, B, and C. 


This is what you started with when you plug A, B, and C, back together. CONGRATS.

SV#5 - Unit J Concepts 3-4: Matrices



A viewer must pay attention to how they write their equations. Don't mistake a Z for a 2! Make you can look for equations to be simplified to make your life a little easier. A viewer must make sure to do their math correctly in the steps or your answer will be wrong and you will be very frustrated. Also, when plugging the equation in to your calculator, make sure you put the numbers in correctly or it won't match up your pair.

SV#4: Unit I Concept 2: Solving and Graphing Log Equations



The viewer needs to pay attention to the graphing the asymptote, as X creates a vertical line. Also, the viewer must acknowledge that you have to exponentiate the log in order to solve for the x-intercept. The viewer must know the different between how to find h, and that it is opposite of what it is in the equation. Lastly, the viewer needs to understand how to plug in points into the calculator and how to use the log base formula.

SP #3 Unit I Concept 1:Graphing Exponential Functions

The viewer needs to pay attention to solving the x-intercept. If you get a negative log, you have to make sure to know that you cannot take the log of something. Therefore, the x intercept is undefined and there is no x-intercept. Also you must acknowledge that the range changes all the time because it depends on the asymptote. If it the graph is below the asymptote, the  graph will go up until the asymptote. If it is above, it will start at the asymptote to infinity.
