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
1(TRNS)j(sbstit)cv-b,
v!.(=)fw
