RESULTANT
Type:
Pimction
Description:
Returns the resultant of two polyiromials of the current
variable. That is, it returns the determinant of the
Sylvester matrices of the two polynomials.
Access:
Catalog, (C®
Input:
Level 2/Argument 1: The first polynomial.
Level l/Argument 2: The second polynomial.
Output:
The determinant of the two matrices that con'espond to
the polynomials.
Flags:
Exact mode must be set (flag -105 clear).
Numeric mode must not be set (flag -03 clear).
RISCH
Type:
Function
Description:
Performs symbolic integration on a frmction using the
Risch algorithm. RISCH is similar to the INTVX
cormnand, except that it allows you to specify the
variable of integration.
Access:

Input:
Level 2/Argument 1: The function to integrate.
Level 1/Argument 2: The variable of integration.
Output:
The antiderivative of the frmction with respect to the
variable.
Flags:
Exact mode must be set (flag -105 clear).
Niuneric mode must not be set (flag -03 clear).
