Hello !! Excuse me,but my english is very poor. I will write in portuguese. If you can help me, thanks.
Eu quero "cancelar" um elemento de uma equa��o. Exemplo: $\frac{x(x+1)}{x}$. Eu queria cancelar o "x" em evid�ncia no numerador com o "x" do denominador. Como fa�o isso no LyX ? Como posso criar um atalho para esse tipo de coisa ?
If somedody can translate this e-mail to english I will thank.
Thank You,
Approximate translation (courtesy of BabelFish):
I want to "cancel" an element of an equation. Example: $\frac{x(x+1)}{x}$. I want to cancel "x" in the numerator with "x" in the denominator. How can I make this happen in LyX?
How I can create a shortcut for this type of thing?
My answer (which wiser minds can correct): This sounds like a job for a computer algebra system (Mathematica or Maple, for instance), not a job for LyX. With the cursor inside a math insert in LyX, you can select Edit -> Math -> Use Computer Algebra System -> ... and pick the system you are using. This of course assumes you have one of the choices installed.
