SV:5 Unit J Concepts 3-4: Solving three variable system with Gaussian Elimination
The viewer needs to pay attention for any mistakes. The goal is to turn the three variable equation into row echelon form. To get the zeros first go to the bottom left, left middle and bottom middle. Make sure to use the RREF to get an idea of what z equals.
SV:4 Unit I Concept 2: Graphing logarithmic functions
The viewer needs to pay attention for any mistakes. Remember to add arrows at the end of the graph. Also calculator won't give an accurate graph so don't copy the calculator. X=h for the asymptote and the range has no restrictions.
SP:5 Unit J Concept 6: Partial Fraction Decomposition with repeated factors
Pay special attention for any mistakes. This concept deals with repeated factors to you must count up the powers. Set up the factors in A,B,C, etc. letters. Towards the end use the calculator in RREF to get the answer to do back substitution to check your answer is right.
SP:4 Unit J Concept 5: Partial Fraction decomposition with distinct factors
Pay spacial attention for any mistakes. Make sure to separate the denominators with letters (A,B,C, etc). Multiply each denominator with what its missing and group all the like terms. At the end make sure to put A,B,C, etc. back to its corresponding fractions from the beginning.

SV:3 Unit H Concept 7
The viewer needs to pay attention for mistake. Always add the log that equals one because that's an extra clue to find the treasure. Remember multiplying in expanding is adding when dividing is subtracting.
SV:2 Unit G Concepts 1-7
The viewers has to pay attention for any mistakes. Know when it's a slant asymptote and when theirs holes. Make sure to add three key points to have an accurate graph.
SV:1 Unit F Concept 10
The viewer needs to pay attention for any mistakes I make. Make sure to dived by P/Q not Q/P. Pay extra attention to the part of the reminder theorem and when using the P/Qs.

SP#3 Unit I Concept 1: Graphing exponential functions and identifying x and y-intercept, asymptotes, domain, range
In concept 1 you'll be able to graph exponential and logarithmic functions from unit H. The graph includes intercepts, asymptotes, domain, and range. it not like other graph from algebra 1 or 2.
Always remember the the phrase YaK Died to get the asymptotes. Solve carefully because this graph doesn't include an x-intercept and don't just leave the answer but explain why. This graph has no restrictions on the domain.
