error in factor
Hi, I have a problem with the factor() function: Consider the following code:
%display latex
j_00 = 1/2*(a^2 + eta)*(a^2 + zeta)/((a^2 - b^2)*(a^2 - c^2)*sqrt((a^2 + eta)*(a^2 + xi)*(a^2 + zeta)/((a^2 - b^2)*(a^2 - c^2))))
show(j_00)
j_00_simplified = j_00.canonicalize_radical().factor())
print(j_00_simplified)As a result, I get:
1/2*sqrt(a^2 + eta)*sqrt(a^2 + zeta)/(sqrt(a^2 + xi)*sqrt(a + b)*sqrt(a + c)*sqrt(-a + b)*sqrt(-a + c))The result is false! It should be:
1/2*sqrt(a^2 + eta)*sqrt(a^2 + zeta)/(sqrt(a^2 + xi)*sqrt(b^2-a^2)*sqrt(a^2 - c^2))The term -a+c is wrong, it should be c-a.
I think this is an error, or is there anything I don't see?
If it is an error, what can I do that factor() returns the expected result?
Thank's in adcance,
Hans
Edited for legibility.
When you need to insert a block of code, indent it by four spaces (or select it an hit
Ctrl-K) (or use the101010button). Inline code can be surrounded by backticks (`).[ Edited as an answer. Sorry for the noise... ].
What's the difference between
-a+candc-a? Maybe I'm misunderstanding.
