u absExpand (absExp)
Function: Divides an expression that contains an absolute value into two expressions.
Syntax: absExpand( {Eq/Ineq} [ ) ]
○ ○ ○ ○ ○
Example
To strip the absolute value from | 2X – 3 | = 9
3(EQUA)j(absExp)K5(Abs)(
c
v-d)!.(=)jw
u andConnect (andCon)
Function: Connects two inequalities into a single expression.
Syntax: andConnect( Ineq-1, Ineq-2 [ ) ]
○ ○ ○ ○ ○
Example
To combine X > – 1 and X < 3 into a single inequality
3(EQUA)v(andCon)v3(EQUA)b(INEQUA)b(>)
-b,v3(EQUA)b(INEQUA)c(<)dw
–1 < X < 3
u eqn
Function: Recalls eqn memory contents.
Syntax: eqn( memory number [ ) ]
○ ○ ○ ○ ○
Example
To add 15 to both sides of the equation 6X – 15 = X – 7, which is stored
in equation memory 3
4(eqn)d)+bfw
6X = X + 8
2X – 3 = 9
or 2X – 3 = – 9
