SV#5 Unit J Concept 3-4: Solving three- variable systems with Gaussian Elimination and Solving non- square systems

     The trickiest part for doing matrx is the math. As in the multiplying  and adding or subtraction to get a zero on where they have to be. Also as you can see here I got 0001 but I got 00011 and that is because in the calculator I put rref as the reduced form thats why I got confused but my answer is still right. Well hope this helped thanks for watching. :D

SV#4 Unit I Concept 2 - Graphing Logarithmic Functions

;

     The trickiest part of this concept is putting it in the calculator right because parenthesis matter a lot if you forget your answer will be totally different. The y intercept is tricky too because when it comes with the log people think its a times not an exponent so they get it wrong and when they see that its an exponent they get stuck there. When that happens you have to use the natural log its in your calculator and you divide them. So at the numerator it should be the exponent and at the denominator it is the base.

SV #3 Unit H Concept 7- Finding Logs Given Approximation

           

      So first you have the clues to find your treasure which is the color green. You first multiply to see if you can reduce that to be able to get some of your clues. When you do find your clues you put them in log form. The tricky part of this is the log base 9 to 7 to the 3rd power you can change that to make it look easier to you and make you understand it as well.
      You would put the exponent in the front which is 3 so it would be 3 log base 9 to 7. Then you look at the logs and see where should go where so you can put the right letter where it needs to be. Don't forget when you have 3 log base to 7 in this case log base 9 to 7 is R BUT don't forget the 3 in the front so it should be 3R plus your other answers that you had. ALSO DON'T FORGET THAT SOME ARE - BECAUSE OF THE DIVISION SIGN. Thanks for Watching!!!! :D

SV#2 Unit G Concept 1-7- Finding all parts and graphing a rational function

   

          Hi my name is Derik and this is Unit G Concept 1-7. This Video will show you how to Figure out the Vertical and Slant Asymptotes and as well as the holes if there is something canceled out in the equation if not then there will not be a hole at all. You will also learn how to graph them as well and how they are  suppose to look like.
          The tricky part for me was the calculator because in this problem it looked the right side was a positive infinity but at the same time it also looked like a negative infinity. It just got very confusing for me at that point now. I go know though that the extra numbers you have to to plot more to make a line in the calculator i know how to do that. Other than that if you follow these steps and listen you will get it. Thanks for watching..

SV#1 Unit F Concept 10- Finding all real and imaginary zeroes of a polynomial

       First you find the p's and q's then divide p/q and find the possible zeroes. right after that you use the decartes rule of sign to which how many possible zeroes you will get. Use synthetic division until you find a zero hero you keep going until your able to distribute it or you cant anymore.
      Then use the quadratic formula -b+or- the square root of b^2 -4(a)(c)/ 2(A). you will either get a perfect square or a imaginary number but you usually always get an imaginary number. You find the zeroes which are the numbers that equaled to zero in your synthetic division and quadratic formula you put and x-then your quadratic answer your suppose to get two different answers. Then the factors is the equation you reduced while doing the synthetic division and the quadratic but you dont put x- on it. Thanks for watching!!!!!!!
