SINH
Type: Analytic function
Description: Hyperbolic Sine Analytic Function: Returns the hyperbolic sine of the argument.
For complex arguments, sinh(x + iy) = sinhx cosy + i coshx siny.
Access: …Ñ HYPERBOLIC SINH (Ñ is the right-shift of the 8key).
!´ HYPERBOLIC SINH ( ´ is the left-shift of the Pkey).

SINV
Type: Command
Description: Store Inverse Command: Replaces the contents of the named variable with its inverse.
The named object must be a number, a matrix, an algebraic object, or a unit object. For
information on reciprocals, see INV.

SIZE
Type: Command Operation
Description: Size Command: Returns the number of characters in a string, the number of digits in an integer,
the number of elements in a list, the dimensions of an array, the number of objects in a unit
object or algebraic object, or the dimensions of a graphics object.
The size of a unit is computed as follows: the scalar (+1), the underscore (+1), each unit name
(+1), operator or exponent (+1), and each prefix (+2).
Any object type not listed above returns a value of 1.
Access: !° L CHARS SIZE ( °is the left-shift of the Nkey).
