HP 48gII Graphing manual Polynomial, Pop, Form of Current Plotting Action Equation, Access …µPOLAR

•res is a real number specifying the interval, in user unit coordinates, between values of the independent variable. The default value is 0, which specifies an interval of 2 degrees, 2 grads, or π/90 radians.

•axes is a list containing one or more of the following, in the order listed: a complex number specifying the userunit coordinates of the plot or igin, a list specifying the tickmark annotation, and two strings specifying labels for the horizontal and vertical axes. The default value is (0,0).

•ptype is a command name specifying the plot type. Executing the command POLAR places the name POLAR in ptype.

•depend is a name specifying a label for the vertical axis. The default value is Y.

The current equation is plotted as a function of the variable specified in indep. The minimum and maximum values of the independent variable (the plotting range) can be specified in indep; otherwise, the default minimum value is 0 and the default maximum value corresponds to one full circle in the current angle mode (360 degrees, 400 grads, or 2π radians). Lines are drawn between plotted points unless flag –31 is set.

If flag –28 is set, all equations are plotted simultaneously.

If EQ contains an expression or program, the expression or program is evaluated in Numerical Results mode for each value of the independent variable to give the values of the dependent variable. If EQ contains an equation, the plotting action depends on the form of the equation.

Equation
expr = expr	Each expression is plotted separately. The intersection of the
	two graphs shows where the expressions are equal
name = expr	Only the expression is plotted

POLYNOMIAL

Type:	Command
Description:	Displays a menu or list of CAS operations with polynomials.
Access:	Catalog, …µ
Flags:	If the CHOOSE boxes flag is clear (flag –117 clear), displays the operations as a numbered list. If
	the flag is set, displays the operations as a menu of function keys.

POP	Command
Type:
Description:	Restores the flags and current directory saved by the most recent execution of PUSH. If no
	PUSH saves are left, the command has no effect.
Access:	…µ POP
Input:	None
Output:	In Algebraic mode the command returns NOVAL to level 1 of the stack.
