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 – X2 to the left side

3(EQUA)e(rewrit)v+d!.(=)

f

v-vxw

X2

– 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(>)

f

a+(X)-ca-(Y)w

5X – 2Y < 3
