Well, thanks God the problem is solved, the error:

'sage.rings.integer.Integer' object is not callable


was something due to the initial estimation being in the form of a constant number, instead of a function, so that calling it by (x=, ) was nonsense to sage as is a function like 24(x=, ) ! The question about t being positive or negative is also resolved automatically after the initial estimation was set as a function, like e.g. a*x+b putting 'a' equal to zero at the end of the computations, although not a very good way to get rid of that error but anyway that was the only way I found for the code just to work! Thanks
