## ANS

Type:
Command
Description: Recalls the nth answer from history (algebraic mode only), where n is an integer. In RPN mode, it
performs the LASTARG command.
Access:
Input/Output:
LAST, LASTARG

### APPLY

Type:
Function
Description: Apply to Arguments Function: Creates an expression from the specified function name and
arguments.
A user-defined function f that checks its arguments for special cases often can ' t determine
whether a symbolic argument x represents one of the special cases. The function f can use
APPLY to create a new expression f(x). If the user now evaluates f(x), x is evaluated before f, so
the argument to f will be the result obtained by evaluating x.
When evaluated in an algebraic expression, APPLY evaluates the arguments (to resolve local
names in user-defined functions) before creating the new object.

### ARC

Type:
Command
Description: Draw Arc Command: Draws an arc in PICT counterclockwise from x
the coordinate specified in argument 1 or level 4 and its radius specified in argument 2 or level 3.
ARC always draws an arc of constant radius in pixels, even when the radius and center are
specified in user-units, regardless of the relative scales in user-units of the x- and y-axes. With
user-unit arguments, the arc starts at the pixel specified by (x, y) + (a, b), where (a, b) is the
rectangular conversion of the polar coordinate (x
the starting point to the centre pixel is used as the actual radius, r'. The arc stops at the pixel
specified by (r', x
