Syntax

COLLECT ( equation, symbol )


Implemented in iMath since version 2.2.0 or earlier.

Explanation

Try to restructure both sides of the equation as a polynomial in the given variable. The variable may be omitted, in which case iMath uses the variable that occurs in the greatest amount of powers.


Example

COLLECT ( x y + x^2 y + y^2 x = 0, x) will give the result (y^2 + y) x + x^2 y = 0.

COLLECT ( x y + x^2 y + y^2 x = 0, y) will give the result (x^2 + x) y + x y^2 = 0.
