Determinants
... To illustrate the method of second-order determinants, we will assume two loop equations as follows: 10I1 + 5I2 = 15 2I1 + 4I2 = 8 We want to find the value of I1 and I2. To do so, we form a determinant with the coefficients of the unknown currents. A coefficient is the number associated with an unk ...

... 5. In a sports league there are four teams and every team plays every other team once. A team scores 3 points for a win, 1 point for a draw, and 0 points for a loss. What is the smallest number of points a team could have at the end of the league and still score more points than each of the other te ...

Chapter 3: The Inverse
... Thus, to calculate the inverse we need to keep a record of the elementary matrices. This is accomplished by applying the same elementary operations to both A and an identity matrix since (Ek Ek-1 … E3 E2 E1)I = Ek Ek-1 … E3 E2 E1 = A-1 ...

... or false, we check to see that both elements, or members of the sentence name the same number. To decide whether a closed sentence containing an sign is true or false, we check to see that both elements do not name the same number. The relation of equality between two numbers satisfies the followi ...
