RISCH
Type: Function
Description: Performs symbolic integration on a function using the Risch algorithm. RISCH is similar to the
INTVX command, except that it allows you to specify the variable of integration.
Access: Calculus !Ö DERIV . & INTEG L.
Input: Level 2/Argument 1: The function to integrate.
Level 1/Argument 2: The variable of integration.
Output: The antiderivative of the function with respect to the variable.
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 antiderivative of the following function, with respect to y:
y
2
3y 2+ +
Command: RISCH(Y^2-3*Y+2,Y)
Result: 1/3*Y^3-3*(1/2*Y^2)+2*Y
