| 2023-09-25 01:37:48 +0200 | marked best answer | Real and imaginary part of an expression with assumptions on variables Hello, I have this expression: All variables are real except nu which is a complex number. I want the real part and the imaginary part of this expression. I tried with Wolfram Alpha and either it assumes all variables are complex, or, of I specify some Assumptions, it does not return the result. Is it possible with Sage ? I'm very new to Sage. I'm new to GIAC too and I didn't found how to force a variable to be real. |
