SP5: Unit J Concept 6: Partial fraction decomposition with repeated factors






This problem deals with solving partial fraction decomposition with repeated factors. The viewer needs to pay special attention to the repeated factors, they must count up the powers and include the factors as many times as the exponent. They should also be very careful with their signs, whenever distributing or substituting. Another important thing is that the answers gotten for a, b, c, etc, are put in the split up fraction from the beginning. Also the more letter involved the more equations there will be. These are the most important things to keep in mind when doing the problem. :)




SP4: Unit J Concept 5: Partial fraction decomposition with distinct factors







   This problem problem involves partial fraction decomposition of distinct factors. The viewer should pay close attention to the instructions for the calculator, and that when you go 2nd quit and then 2nd matrx you go to math all the way down to RREF then continue the steps. Something else would be to be very careful with your signs and everything plugged into the calculator, because one tiny mistake can cause you to get everything wrong. We don't want all this work to go to waste and start all over so be careful. Another thing would be to always forget to get rid of the x's when you have grouped like terms.

SV#5: unit I concept 3: solving three variable systems with Gauss Jordan elimination, matrices, row echelon form, and back substitution.

Click HERE to watch the video:)

This video deals with matrices and how they help you easily solve them in three simple steps. Then using row echelon form to help you check your answer. Then using back substitution to find your ordered pair. The viewer should pay close attention to the rows I utilized, and the way I managed to get the three zeroes and the row of ones. Another thing would be the directions on how to check your answer on the calculator. Be very careful on tiny errors like forgetting minus signs.
