2020-06-05 12:03:28 +0200 | asked a question | Why does Sage say my Groebner basis is 1? Consider the following program So $a_1, a_2, a_3, l_2, l_3$ are parameters, and I am trying to solve the system of equations $$a_1 = l_3s_1s_2 + l_2c_1 $$ $$a_2 = l_3s_1c_2 - l_2s_1$$ $$a_3 = l_3c_2$$ $$c_1^2 + s_1^1 = 1$$ $$c_2^2 + s_2^2 = 1$$ Now this gives as result 1, meaning that there is no solution to this system. However, for $a_1 = l_2$, $a_2 = 0$ and $a_3 = l_3$ we do have a solution, namely $c_1 = 1, s_1 = 0, c_2 = 1, s_2 = 0$. So is something in the programming going wrong, or am I misunderstanding something on the algebraic geometry part? |

2020-05-02 23:34:06 +0200 | asked a question | Running a prewritten program In Python you have IDLE, which allows you to write a program and then run it. I am looking for something similar for sage, so that you don't have to type it line for line in sagemath. Is there something that looks like IDLE for sage? I had a look at this the programmig page of the docs (I cannot post the link due to 'karma' whatever that is), and tried to do it by creating a program in a .txt file and then renaming it to .sage, but sage said that it could not find the file. The error says OSError: did not find file 'C:\Users\Martin\Desktop\example.sage' to load or attach and the exact thing I wrote is load("C:\Users\Martin\Desktop\example.sage") I double checked the path and file name, I am pretty sure that there are no mistakes in that. |
