Hello
I'm solving Einstein equation in vacuum. I already computed the Ricci tensor. For example, de first Ricci component is saved in the following variable eq1:
eq1=EE[0,0]
The denominator of the component should vanish since since the other part of the equation is zero. How can I extract numerator of the expression. I have tried:
eq1.denominator()
But it does not work.Thanks
