# Finding Re() and Im() for complex numbers

Hey guys,

Is there a way to find the real and imaginary parts of a complex number in Sage? If so, how is it done?

Thanks.

.real() for real part .imag() for imaginary part

For eg.

```
(3+i*4).real()=3
(3+i*4).imag()=4
```

real_part(z) and imag_part(z) also work.

check if the result is a real number

How does sage deal with choosing branches? Examples?

exponential equation real solution

Differentiating Complex Conjugated Functions

Additional conditions for expression

Complex forms and differentials

solve gives 1, 2, or 3 answers depending if one value in my equation is a real, rational, or integer
