Description: Returns the inverse Laplace transform of an expression. The expression must evaluate to a
rational fraction.
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: Find the inverse Laplace transform of:
Command:
ILAP(1/(X-5)^2)
Result: X*EXP(5*X)
