SIN

Sin is the short version of the trigonometry SINE() function. This short version is always used in equations and expressions since it takes less space. Used in an equation it might look like

sin x = 0.22
This would be interpreted as "The sine of x is 0.22". Most mathematicians would speak it as "sine x equals 0.22". (It is never pronounced 'sin'.)
