Recently, when I have been trying to use the simplify command (and this has occurred with other functions), the SageMath kernel crashes with the error "unhandled lisp initialization error". Does anyone know why this is happening? Do you have a solution?

That indicates there is something broken in your installation. The expected output is:

sage: f =cos(x)^2+sin(x)^2
sage: f
cos(x)^2 + sin(x)^2
sage: f.full_simplify()

The first thing to try is to reinstall sage, since this indicates something rather fundamental is broken (at least for the maxima/lisp subsystem that is used for simplification). If that doesn't help, you might get help by giving exact details about your operating system and the way you've installed sage. https://groups.google.com/forum/#!for... is probably a better forum to get help for this.

Thank you nbruin for your comment. This resulted in the fix I needed, just a reinstallation of SageMath. Now I am getting the results as expected.
