How do you multiply a vector by a scalar?
To multiply a vector by a scalar, multiply each component by the scalar. If →u=⟨u1,u2⟩ has a magnitude |→u| and direction d , then n→u=n⟨u1,u2⟩=⟨nu1,nu2⟩ where n is a positive real number, the magnitude is |n→u| , and its direction is d .
Can you multiply a set by a scalar?
Scalar multiplication obeys the following rules (vector in boldface): Additivity in the scalar: (c + d)v = cv + dv; Additivity in the vector: c(v + w) = cv + cw; Compatibility of product of scalars with scalar multiplication: (cd)v = c(dv);
Can you multiply matrices in Excel?

How do you multiply a vector?
Multiplying a Vector by a Matrix To multiply a row vector by a column vector, the row vector must have as many columns as the column vector has rows. Let us define the multiplication between a matrix A and a vector x in which the number of columns in A equals the number of rows in x . So, if A is an m
