Sound energy is mechanical, it involves the movement of atoms. The energy in a sound wave is both kinetic and potential. Just as in a vibrating spring, the medium has mass a â¦ nd moves and so moving mass is kinetic energy. Just as in the spring there is compression and rarefaction, so there is elastic potential energy.
A polynomial is a mathematical expression consisting of a sum of terms, each term including a variable or variables raised to a power and multiplied by a coefficient. The simplest polynomials have one variable. anxn + an-1xn-1 + ... where the a's represent the coefficients and x represents the variable.
Polynomials: Definitions / Evaluation (page 1 of 2). Sections: Polynomial basics, Combining like terms. By now, you should be familiar with variables and exponents, and you may have dealt with expressions like 3x4 or 6x. Polynomials are sums of these variables and exponents expressions. Each piece of the polynomial, each part that is being added, is called a term. Polynomial terms have variables which are raised to whole-number exponents (or else the terms are just plain numbers); there are no square roots of variables, no fractional powers, and no variables in the denominator of any fractions.
