Linear Equations in Two Variables
A linear equation in 2 variables is a straight line on a graph. A system of 2 Linear equations in 2 variables –A1x + B1y = C1A2x + B2y = C2The 2 lines will be parallel to each other if (A1 * B2) – (B1 * A2) = 0 If (A1 * B2) – (B1 …
Dimensions
Below thoughts have been written for my personal record. Those might be true, false, right, wrong, sane, insane etc. Consider a classic X-axis. It is divided into infinite discrete parts. Consider a classic Y-axis. It is also divided into infinite discrete parts. Consider a classic X-Y plane and think about these co-ordinates : (1, -infinity ) (1, -93459485 …
