u combine (combin)

Function: Adds and reduces rational expressions.

Syntax: combine( {Exp/Eq/Ineq/List/Mat/Vect} [ ) ]

○ ○ ○ ○ ○

Example

To reduce the fraction (X + 1) / (X + 2) + X

(X + 3)

1(TRNS)h(combin)(v+b)/

(

v+c)+v(v+dw

u collect (collct)

Function: Rearranges an expression, focusing on a particular variable.

Syntax: collect( {Exp/Eq/Ineq/List/Mat/Vect} [,{Exp/variable}] [ ) ]

○ ○ ○ ○ ○

Example

To rearrange X2 + AX + BX, focusing on the variable X

1(TRNS)i(collct)vx+av(A)v+

al(B)vw

X2

+ (A + B)X

• X is the default when nothing is specified for [,{Exp/variable}].

u substitute (sbstit)

Function: Assigns an expression to a variable.

Syntax: substitute( {Exp/Eq/Ineq/List/Mat/Vect}, variable=expression

[,..., variable=expression] [ ) ]

○ ○ ○ ○ ○

Example

To assign 5 to X in 2X – 1
