Partial Fraction Decomposition


Best Answer azogtoth , 15 February 2017 - 12:46 PM

found it! Try:

 

expand(1/(x^2-1),x)​

 

Btw, I like typing

 

expand(1/(xx-1),x)​

 

xx is easier to type than x^2, but works the same :nod:

Hello,

 

I need to do partial fraction decomposition:

 

simple example:

1/(x^2-1) -> (1/2)/(x-1) + (-1/2)/(x+1)

 

I was hoping expand(1/(x^2-1)) would do the trick, but unfortunately...

 

Does anyone know if there is a function on that can do this?

 

Otherwise, I'd have to write my own function to do this. But I struggle with how to pass a function to my function ;)

 

Cheers,

Stefan
