Numbered musical notation and so on. Dashes after a note lengthen it, each dash by the length of a quarter note. A dot after the plain or underlined note works increases its length by half, and two dots by three quarters. The underline, along with its joining, are analogous to the number of flags and beaming in standard notation. So are dotted notes. But the analogue stops at notes worth three quarter notes and beyond, where dashes are used instead. The number "0" represents the musical rest. The rules for length is similar to that of the note, except that it is customary
Notation for differentiation and solving linear differential equations, as it simplifies presentation of the differential equation, which can make seeing the essential elements of the problem easier. Euler's notation can be used for antidifferentiation in the same way that Lagrange's notation is. as follows Newton's notation for differentiation (also called the dot notation for differentiation) places a dot over the dependent variable. That is, if "y" is a function of "t", then the derivative of "y" with respect to "t" is Higher derivatives are represented using multiple dots, as in Newton extended this idea quite far: Unicode characters related to Newton's notation include:
