    I was hoping that someone could point me in the right direction on how I could start answering the following question: Based on the fact that det(AB) = det(A) det(B) det (A B) = det (A) det (B) for all square n × n n × n matrices A, B A, B, explain in every detail why:

    There are many important properties of determinants. Since many of these properties involve the row operations discussed in Chapter 1, we recall that definition now. We will now consider the effect …
  3. D-system breakdown of 1st DET goal last night. 7 secs from center ice to the goal. I know we won, but here's a quick look at the 1st goal against last night, at 4:41 into 1st period, to see how DET undressed us inside 7 seconds, and more on the positioning of the OTHER THREE if we want to play a 2-on-1 overload D.
  4. SCH: Crit vs Det breakdown? Hi there. Does anyone know if any testing has been done for crit/det values? I've tried to find some stuff via google, but found nothing recent (only outdated phase 3 stuff). Specifically, I'd like to compare Determination and Critical Rate on SCH, considering the additional effect of Adloquiem.

    Normal is the base game story line, breakdown is a sandbox that has a mechanic that resets the map making it harder each time (basically you repair an RV and drive off with a few people & the map resets, each time getting less resources and more stronger zombies). Lifeline is a story based much more action orientated story from the side of the military.

  1. A

    Assuming that the matrix A is invertible, we know that:

    $$AA^{-1} = I$$

    $$\text{det}(AA^{-1}) = \text{det}(I)$$

    Now we use $\text{det}(A*A^{-1}) = \text{det}(A)*\text{det}(A^{-1})$ and $\text{det}(I) = 1$ :

    $$\text{det}(A)*\text{det}(A^{-1}) = 1 \implies \text{det}(A^{-1}) = 1/\text{det}(A)$$
