the cross product will be 0. If both vectors are normalized, and they are perpendicular to each other, the cross product will be 1 (if the angle from a to b is 90°) or -1 (if the angle is 270°).
Linear Combination of Vectors The above definition also extends to vectors. Let’s say that you have two vectors v and w; Each vector is multiplied by a scalar a and b, giving the expression: av + bw. The expression av + bw is called a linear combination of v and w. Using a little...
You could also use to “many to one” rule: Is a function: “many to one“. This is saying if you have multiple x-values that map to one y-value — say, (2,9), (3,9) and (6,9) — then that still qualifies as a function. Put more simply, it’s okay for a function to...
