Simulate an equation for different values
Example
Find the area S = bc sin A ÷ 2 when:
1 b = 3, c = 5 and A = 90° (DEG)
2 b = 3, c = 5 and A = 45° (DEG)
3 b = 4, c = 5 and A = 45° (DEG)
1. Press b 0 to select the NORMAL mode.
2. Press @ J 0 0 j.
• Sets the angular unit to DEG.
3. Press ; B ; C v
; A z 2.
• The equation is entered in the normal
way.
4. Press @ G.
• The calculator automatically calls the
display for entering variables and picks
out the variables in alphabetical order.
• If a variable already has a value, the
calculator displays that value automati-
cally.
