2013-10-31 07:59:09 -0500 | marked best answer | Why Sage cannot pass a value of variable from one function to another nested function? I'm not sure what you think is wrong here. The 2 and a factor of -1 were both factored out, that's all. However, I do agree that this doesn't expand. What is happening is that we are sending the sum to Maxima and then ordinarily when it returns, it is still a Maxima object (which may be a bug?). But when we put it in the function, it becomes a Sage object - but we don't have a Sage "sum" object. So I think that is what would have to be fixed. That this is |

2013-10-31 07:58:54 -0500 | commented answer | Why Sage cannot pass a value of variable from one function to another nested function? That mean i cannot define the function like that right? It will be very nice if i can define it similar to the second example. it will be consistent with the real equation on my paper. |

2013-10-31 07:09:56 -0500 | asked a question | Why Sage cannot pass a value of variable from one function to another nested function? The first i ran this: So, In this case the result was evaluated correctly. But if i tried to combine the first line and the second line together: The result wasn't finished! Why sage cannot evaluate mathematical expression in this case? Another tried to prove that Sage can pass its variable from left function to right function even though the right function was a nested function: Edit: (See the same question on SO.) |
