The Cool S is a graffiti sign in popular culture that is typically doodled on children's notebooks or graffitied on walls. The exact origin of the Cool S is unknown, but an instance was found in an 1890 geometry textbook and it became prevalent around the early 1970s as a part of graffiti culture.
Despite its prevalence across the globe and throughout the 20th century, the origin stories for the “S” remain shrouded in mystery. Some believe it is derived from Los Angeles gang culture. Others point to various bands that may have used it in their logos. Finally, it may just be a reworked infinity symbol.
What's That 'S' Thing Everyone Drew in School? "The reason kids go through this is probably because it's a Moebius strip," he said, referring to the sort of looped one-surface shapes M. C. Escher was fond of drawing. "It can't be drawn continuously, but it does have a perpetual flow."
Share. The section sign, also called a silcrow, is a typographic mark used to reference a particular section of a document. Its shape derives from a double 's', which in Latin stands for signum sectionis (meaning 'section symbol').
s is used to denote the standard deviation of a sample of scores. The formula for the standard deviation differs slightly, depending on whether it is the population s.d., the sample s.d., or the sample mean used as an estimate of the population s.d..
Ṡ (lowercase: ṡ or ẛ) is a letter of the extended Latin alphabet, formed by S with the addition of a dot above.
It is used in Lakota, Cheyenne, and Cree (in dialects such as Moose Cree), Classical Malay (until end of 19th century) and some African languages such as Northern Sotho and Songhay.
S-cedilla (majuscule: Ş, minuscule: ş) is a letter used in some of the Turkic languages. It occurs in the Azerbaijani, Gagauz, Turkish, and Turkmen alphabets. It is also planned to be in the Latin-based Kazakh alphabet.
The section sign, §, is a typographical character for referencing individually numbered sections of a document; it is frequently used when citing sections of a legal code.

D.S. means go back to the sign (fancy "S") which is in measure 5 and play until you reach the first coda symbol. That means you play measures 5-11 again.
The S probably means "slide" which is another word for glissando. In your example only one of them has a wavy line but they should probably all have a wavy line.
The symbol ∑ indicates summation and is used as a shorthand notation for the sum of terms that follow a pattern. For example, the sum of the first 4 squared integers, 12+22+32+42, follows a simple pattern: each term is of the form i2, and we add up values from i=1 to i=4.
Consequently, the standard deviation calculated for population data is denoted by σ and the standard deviation calculated for sample data is denoted by s. where σ is the standard deviation of the population and s is the standard deviation of the sample.
The symbol 'μ' represents the population mean. The symbol 'Σ Xi' represents the sum of all scores present in the population (say, in this case) X1 X2 X3 and so on.
The long s ⟨ſ⟩, also known as the medial s or initial s, is an archaic form of the lowercase letter ⟨s⟩. It replaced the single s, or one or both of the letters s in a "double s" sequence (e.g., "ſinfulneſs" for "sinfulness" and "poſſeſs" or "poſseſs" for "possess", but never *"poſſeſſ").
