read moreIn Direct Variation, only one variable x is multiplied by a constant k called the constant of variation. Therefore the formula for Direct Variation is y=kx. The input variable x multiplied by the constant of variation k gives the output y.
read moreA Real Vector Space is a Vector Space whose vectors are described by real numbers. We can describe our classical three-dimensional space as simply a Vector Space with three degrees of freedom – or dimensions. Such a space would be labeled: This…

read moreA scalar function is a function of one or more variables whose range is one-dimensional, as compared to a vector function, whose range is three-dimensional (or, in general, n-dimensional).
read moreA scalar is a quantity that has magnitude but no direction. It is a single-dimensional quantity.
read moreA Vector Space is a set of vectors that may be added together and scaled. When we say they may be scaled, we mean that they may be multiplied by numbers called scalars. For example, we may multiply all of the vectors…
