Homework Statement
How can you get from this
[tex] \frac {z(i-1) +i +1} {z(1-i) +i +1} [/tex]
to this
[tex] = \frac { z-1 } {-z -i} [/tex]
?
The Attempt at a Solution
SageMath does not simplify the result any further from the beginning.
The equivalence is based on some high Math.
I am not sure how you can deduce the equivalence.
