Integer; Intvx; Invmod - HP 48gII Advanced User's Reference Manual

Input: Level 3/Argument 1: A function.
Level 2/Argument 2: The variable to obtain the derivative with respect to.
Level 1/Argument 3: The point at which to calculate the antiderivative. This point can be a
variable or an expression.
Output: The antiderivative of the function for the given variable, at the point you specified.
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 integral of sin(x) with respect to x, at the point where x=y.
Command:
INT(SIN(X),X,Y)
Result:
-COS(Y)
