u rclEqn
Function: Recalls multiple eqn memory contents.
Syntax: rclEqn( memory number [ , ..., memory number] [ ) ]
○○○○○
Example To recall the contents of equation memory 2 and equation memory 3
3(EQUA)c(rclEqn)c,dw 3X – Y = 7
3X + 6Y = 63
• The memory numbers of equations produced as the result of a recall are not updated.
u rclAllEqn (rclAll)
Function: Recall all eqn memory contents.
Syntax: rclAllEqn
• The memory numbers of equations produced as the result of a recall are not updated.
u rewrite (rewrit)
Function: Moves the right side element to the left side.
Syntax: rewrite( {Eq/Ineq} [ ) ]
○○○○○
Example To move the right side element of X + 3 = 5X – X
2
to the left side
3(EQUA)e(rewrit)v+d!.(=)
fv-vxw X
2
– 4X + 3 = 0
u exchange (exchng)
Function: Exchanges the right-side and left-side elements.
Syntax: exchange( {Eq/Ineq} [ ) ]
○○○○○
Example Exchange the left-side and right-side elements of 3 > 5X – 2Y
3(EQUA)f(exchng)d3(EQUA)b(INEQUA)b(>)
fa+(X)-ca-(Y)w 5X – 2Y < 3
