Access:	Calculus, !ÖDIFFERENTIAL EQNS
Input:	A rational expression.
Output:	The inverse Laplace transformation of the expression.
Flags:	Exact mode must be set (flag –105 clear).
	Numeric mode must not be set (flag –3 clear).
	Radians mode must be set (flag –17 set).
Example:						1
	Find the inverse Laplace transform of:(x – 5)2
						------------------

IM	Function
Type:
Description:	Imaginary Part Function: Returns the imaginary part of its complex argument.
	If the argument is an array, IM returns a real array, the elements of which are equal to the
	imaginary parts of the corresponding elements of the argument array. If the argument array is real,
	all of the elements of the result array are zero.
Access:	…ßIM					(ßis the rightshift of the	1key).
Flags:	Numerical Results (–3)
Input/Output:
				Level 1/Argument 1			Level 1/Item 1
					x	→	0
					(x, y)	→	y
					[ Rarray ]	→	[ Rarray ]
					[ Carray ]	→	[ Rarray ]
					'symb'	→	'IM(symb)'

IMAGE
Type:	Command
Description:	Computes the basis of the image (also called the range) of a linear application f.
Access:	Matrices, !Ø LINEAR APPL
Input:	A matrix representing a linear application f in terms of the standard basis.
Output:	A list of vectors representing a basis of the image of f.
Flags:	Exact mode must be set (flag –105 clear).
	Numeric mode must not be set (flag –3 clear).
