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.
That critter in the last section is a polynomial! Here are some others: Polynomial is a pretty big word, but it's not a hard thing. (We use big words in math so other people think we are smart.. For now (and, probably, forever), you can just think of a polynomial as a bunch of blobs all added or subtracted. The blobs are just products of numbers and letters with exponents. As you'll see later on, polynomials have cool graphs:
