Music uses variables which are called notes. Beats are mesaured by musical notes which are used as variables to determine the pitch of a sound in a part of a song. Musical notes are fascinating because in order to diferentiate between notes it takes ratios and notation to do so. Notes have the letters A, B, C, D, E, F, G but can also differ in each country they have half notes called sharp all this does is raise the note a half a step then it originally is. The notes that are sharp or flat are not on the scale or mode they are like little variables on the side of the notes that are called accidental notes. Notes are used on different instruments which if you use it on one of the instruments it is …show more content…

A beat is steady and regular in pulse and is equally spaced while rythm is not. Rythm does not have to be equally spaced. The difference is that rythm does not have to be limited and it can have more sylables. Metre is the base unit of length in the SI and is one ten-millionth of the distance from the equator to the North Pole discovered in 1793 and is 2.54 centimetres "One metre is about 3 3⁄8 inches longer than a yard, i.e. about 39 3⁄8 inches" that is quoted from wikepedia. Tempo is the speed of the song or music your playing so if I put a song and its going fast, pretty much you would play your instrument at a fast tempo that's all tempo really means. These were just some more measurements of

In \cite{Romauera92}, Romaguera pointed out that if $X=\mathbb{R}^+$ and $p : X \times X\to \mathbb{R}^+$ defined by $p(x, y) = \max\{x, y\}$ for all $x, y \in X$ then ${CB}^p(X)=\emptyset$ and the approach used in Theorem \ref{THM201} and elsewhere has a disadvantage that the fixed point theorems for self-mappings may not be derived from it, when ${CB}^p(X)=\emptyset$. To overcome from this problem he introduced the concept of mixed multi-valued mappings and obtained a different version of Nadler's theorem in a partial metric spaces. \begin{definition} Let $(X, p)$ be a partial metric space. A mapping $T : X \to X \cup {CB}^p(X)$ is called a mixed multi-valued mapping on $X$ if $T$ is a multi-valued mapping on $X$ such that for each $x\in X$

Trigonometry was used by ballistic experts to study the JFK assassination. Trigonometry was used to calculate the trajectory of the bullet shot by Lee Harvey Oswald’s high-powered rifle. Through the study of triangles forensics was able to determine the distance between the bullet shot from the Texas School Book Depository to JFK’s motorcade. Trigonometry also allowed for ballistic experts to calculate the angle in which the angle descended and the velocity of the ammunition. According to www.intuition .com

We work with a Boolean Language whose basic symbols are $\vee,\wedge,\neg,\Rightarrow$ endowed with a finite set of atoms $\mathcal{A}$. The set of literals, $\mathcal{L}$, is the set $\mathcal{A}\cup\{\neg p|p\in\mathcal{A}\}$. A pair formed by a literal together with its negation is called a conjugated pair. Here we give the (classical) definition of valuation over a Boolean formula. That is the definition we will use henceforth. \begin{definition}\label{BOOLFOR:def}
