d/dx

On a Casio calculator you can calculate linear differentials

MATH			d/dx
	F4		F4

or as

	CALC			d/dx
OPTN		F4		F2

or via the CATALOG as

CATALOGP					INPUT
SHIFT		4		d/dx(		F1

You can interrupt an ongoing calculation by pressing  AC^/ON .

Explanation

The syntax for the linear differential command is

d/dx( f (x), a, tol )

where

f (x)	Expression
a	Point of the derivative
tol	Tolerance

For SET UP Input/Output Line you get

MATH			d/dx
	F4		F4		d/dx(

and for SET UP Input/Output Math the tolerance value is fixed at 1E−5 and cannot be changed

MATH			d/dx
	F4		F4		|x=▯
