# How to write a piecewise equation

Obtaining Equations from Piecewise Function Graphs You may be asked to write a piecewise function, given a graph. Polynomials of small degree have been given specific names. A polynomial of degree zero is a constant polynomial or simply a constant. Polynomials of degree one, two or three are respectively linear polynomials, quadratic polynomials and cubic polynomials.

For higher degrees the specific names are not commonly used, although quartic polynomial for degree four and quintic polynomial for degree five are sometimes used. The names for the degrees may be applied to the polynomial or to its terms.

The polynomial 0, which may be considered to have no terms at all, is called the zero polynomial. Unlike other constant polynomials, its degree is not zero. The zero polynomial is also unique in that it is the only polynomial having an infinite number of roots.

In the case of polynomials in more than one indeterminate, a polynomial is called homogeneous of degree n if all its non-zero terms have degree n.

The zero polynomial is homogeneous, and, as homogeneous polynomial, its degree is undefined. For more details, see homogeneous polynomial. The commutative law of addition can be used to rearrange terms into any preferred order. In polynomials with one indeterminate, the terms are usually ordered according to degree, either in "descending powers of x", with the term of largest degree first, or in "ascending powers of x".

The polynomial in the example above is written in descending powers of x. The first term has coefficient 3, indeterminate x, and exponent 2. The third term is a constant. Because the degree of a non-zero polynomial is the largest degree of any one term, this polynomial has degree two.

It may happen that this makes the coefficient 0. The term "quadrinomial" is occasionally used for a four-term polynomial. A real polynomial is a polynomial with real coefficients. The argument of the polynomial is not necessarily so restricted, for instance the s-plane variable in Laplace transforms.

A real polynomial function is a function from the reals to the reals that is defined by a real polynomial. Similarly, an integer polynomial is a polynomial with integer coefficients, and a complex polynomial is a polynomial with complex coefficients.

A polynomial in one indeterminate is called a univariate polynomial, a polynomial in more than one indeterminate is called a multivariate polynomial.

A polynomial with two indeterminates is called a bivariate polynomial. These notions refer more to the kind of polynomials one is generally working with than to individual polynomials; for instance when working with univariate polynomials one does not exclude constant polynomials which may result, for instance, from the subtraction of non-constant polynomialsalthough strictly speaking constant polynomials do not contain any indeterminates at all.

It is possible to further classify multivariate polynomials as bivariate, trivariate, and so on, according to the maximum number of indeterminates allowed. Again, so that the set of objects under consideration be closed under subtraction, a study of trivariate polynomials usually allows bivariate polynomials, and so on.Velocity in math is similar to speed, with only one difference.

April 26, INTRODUCTION. In order to understand the true impact the automobile has had on our society, we would have to go back in time over one hundred years.

The shortest path between two given points in a curved space, assumed to be a differential manifold, can be defined by using the equation for the length of a curve (a function f from an open interval of R to the space), and then minimizing this length between the points using the calculus of blog-mmorpg.com has some minor technical problems, because there is an infinite.

Preface PURPOSE AND PREREQUISITES. This book is intended as a textbook for a course in differential equations with linear algebra, to follow the differential and integral calculus. In this section we will derive the vector and scalar equation of a plane.

We also show how to write the equation of a plane from three points that lie in the plane.
