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.
(For the general form of a polynomial, see Problem 6 below.) 6. The degree of a term is the sum of the exponents of all the variables in that term. In functions of a single variable, such as x, the degree of a term is simply the exponent. Example 2. The term 5x3 is of degree 3 in the variable x. Example 3.
