u lcm

Function: Obtains the least common multiple of two expressions

Syntax: lcm( {Exp/List}, {Exp/List} [ ) ]

○ ○ ○ ○ ○

Example

To obtain the least common multiple of X2 – 1 and X2 + 2X – 3

2(CALC)l(lcm)vx-b,

vx+cv-dw

X3 + 3X2 – X – 3

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 expression to the left side.

Syntax: rewrite( {Eq/Ineq/List} [ ) ]

○ ○ ○ ○ ○

Example

To move the right side expression of X + 3 = 5X – X2 to the left side

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