I want to define a symbolic function in terms of other symbolic functions, like so:
function('psi psi_1 psi_2')
psi = 1/sqrt(2) * (psi_1 + psi_2 * i)
When running the code, I get the error:
TypeError: unsupported operand type(s) for *: 'NewSymbolicFunction' and 'sage.rings.number_field.number_field_element_quadratic.NumberFieldElement_gaussian'
The same error appears when I replace i with a real number.
Is there any fundamental mistake I'm making? If so, what should I do instead? If not, is there a workaround?
The reason I am defining a function like this is because I need to find the derivative of the psi function in terms of derivatives of the latter two functions.
