You can also use the symbolic ring:
sage: var('x,y,z,A,B,k,i,j,m')
(x, y, z, A, B, k, i, j, m)
sage: solve([x == A*i + B*j, y == A*k + B*m, z == B*(j-m) + A*(i-k)],
[z,i,m])
[[z == x - y, i == -(B*j - x)/A, m == -(A*k - y)/B]]

An Expect script could do the job and avoid the command-line (ps)
issue.

Is there an equivalent in Sage to ParallelMap in mathematica?
I am looking a method that applies a given function to a list of
objects for a small presentation of Sage I am prepa

Hi people! Some questions about the documentation
- Are the commands like %latex, %cython, %hide, etcetera listed
somewhere?
- What about those like @interact, ?
- On the search engine at the webpage, some times I type "differential
form" and get nothing while "differential
