HP 39g+ Graphing List functions, Loop functions

TANH	Hyperbolic tangent.
	TANH(value)
ALOG	Antilogarithm (exponential). This is more accurate than
	10^x due to limitations of the power function.
	ALOG(value)
EXP	Natural exponential. This is more accurate than ex due
	to limitations of the power function.
	EXP(value)
EXPM1	Exponent minus 1 : ex – 1 . This is more accurate than
	EXP when x is close to zero.
	EXPM1(value)
LNP1	Natural log plus 1 : ln(x+1). This is more accurate than
	the natural logarithm function when x is close to zero.
	LNP1(value)

List functions

	These functions work on list data. See “List functions” on
	page 14-6.
Loop functions
	The loop functions display a result after evaluating an
	expression a given number of times.
ITERATE	Repeatedly for #times evaluates an expression in terms of
	variable. The value for variable is updated each time,
	starting with initialvalue.
	ITERATE(expression, variable, initialvalue,
	#times)
	Example
	ITERATE(X2,X,2,3) returns 256
