This formula is an example of "direct" variation."Direct variation" means that, in the one term of the formula, the variable is "on top". (By the way, if you see a formula with a " ∝ " character in it instead of an "equals" sign, that character is pronounced as "is directly proportional to", and indicates that they've given you a direct ...

volume. This function is an example of a direct variation. Summary 𝑘 A direct variation is a function defined by an equation of the form where k is a nonzero constant. You can say that y varies directly as x. The constant k is called the constant of variation. Direct Variation Direct variation equations are written in the form _____, where _____ is the _____ (which is also called the constant of proportion). This equation can also be expressed as _____. This form helps us realize that in a direct variation relationship the quotient of y divided by x will always Chapter 1 The Fourier Transform 1.1 Fourier transforms as integrals There are several ways to de ne the Fourier transform of a function f: R !
