| 2014-12-28 12:09:21 +0200 | asked a question | Variables in Sage I started using sage today and I encountered sime strange errors: I declared variables a,b,c,d using var('a,b,c,d'). When I tried to expand ($a^2+b^2)(c^2+d^2)$ (expand($(a^2+b^2)(c^2+d^2$)) I got the following result: $c^4+2c^2d^2+d^4+b^2$, which is obviously not the correct result. Does anyone know why I got this incorrect andwer? |
