WebIn math, a vector is an object that has both a magnitude and a direction. Vectors are often represented by directed line segments, with an initial point and a terminal point. The length of the line segment represents the magnitude of the vector, and the arrowhead pointing in a specific direction represents the direction of the vector. WebThe vector w will be in the span of the given set of vectors if you can write w as a linear combination of the vectors. That is, provided that w is in the span, you will have w = c 1 v 1 + c 2 v 2 + c 3 v 3 w will be in the span if you can find at least one set of solutions for the coefficients.
