Simulate an equation for different values

Example

Find the area S = bc sin A ÷ 2 when:		A
1 b = 3, c = 5 and A = 90° (DEG)
			c
	b
2 b = 3, c = 5 and A = 45° (DEG)		S
3 b = 4, c = 5 and A = 45° (DEG)

1.Press b0to select the NORMAL mode.

S = bc sin A ⎟ 2

2.Press @J00j.

• Sets the angular unit to DEG.

3.	Press ;B ;C v	NORMAL MODE
	;A z2.		0.
•	The equation is entered in the normal	BCsinA©2_
	way.
4. Press @G.
•	The calculator automatically calls the	BCsinA©2
	display for entering variables and picks	A=z	0.
	out the variables in alphabetical order.

•If a variable already has a value, the calculator displays that value automati- cally.

• indicates that there are more variables.

5.Press 90 e.

•The calculator picks out the next variable.

6.Press 3 e5.

• indicates that this is the last variable.

7. Press e.
