6. Manual GraphingkRectangular Coordinate Graph

Inputting the Graph command in the Run-Matrixmode enables drawing of rectangular coordinate graphs.

1.From the Main Menu, enter the Run-Matrixmode.

2.On the Setup screen, change “Input/Output” setting to “Linear”.

3.Configure V-Window settings.

4.Input the commands for drawing the rectangular coordinate graph.

5.Input the function.

Example	Graph y = 2x2 + 3x – 4.
	Use the following V-Window settings.
	Xmin = –5,	Xmax = 5,	Xscale = 2
	Ymin = –10,	Ymax = 10,	Yscale = 5

•Certain functions can be graphed easily using built-in function graphs.

•You can draw graphs of the following built-in scientific functions.

Rectangular Coordinate Graph

• sin x			• cos x	• tan x	• sin–1x
• cos–1x			• tan–1x	• sinh x	• cosh x
• tanh x			• sinh–1x	• cosh–1x	• tanh–1x
• 'x			• x2	• log x	• lnx
• 10x			• ex	• x–1	• 3'x
•	d	(x)	• d2 (x)	• ∫(x)dx
	dx		dx2

Polar Coordinate Graph

• sin θ	• cos θ	• tan θ	• sin–1θ
• cos–1θ	• tan–1θ	• sinh θ	• cosh θ
• tanh θ	• sinh–1θ	• cosh–1θ	• tanh–1θ
• 'θ	• θ 2	• log θ	• lnθ
• 10θ	• eθ	• θ–1	• 3'θ

-Input for x and θ variables is not required for a built-in function.

-When inputting a built-in function, other operators or values cannot be input.
