u eliminate (elim)

Function: Assigns an expression to a variable.

Syntax: eliminate( {Eq/Ineq} -1, variable, Eq-2 [ ) ]

Example To transform Y = 2X + 3 to X= and then substitute 2X + 3Y = 5

3(EQUA)g(elim)ca+(X)+da-(Y)!.(=)

f,a+(X),a-(Y)!.(=)

ca+(X)+dw 4Y – 3 = 5

u getRight (getRgt)

Function: Gets the right-side element.

Syntax: getRight( {Eq/Ineq} [ ) ]

Example To extract the right side element of Y = 2X

+ 3X + 5

3(EQUA)h(getRgt)a-(Y)!.(=)

ca+(X)x+da+(X)+fw 2X

+ 3X + 5

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
