I am not sure i understand you question since you gave two fixed values to `x`

and `x1`

. If you want to find the limit of the function `some_function = (z -> z*z1)`

when `z`

goes to `z1`

, you can define a symbolic variable `z`

function :

```
sage: z1 = 3 + 4*I
sage: some_function(z) = z * z1
sage: some_function
z |--> (4*I + 3)*z
sage: some_function.limit(z=z1)
24*I - 7
```

I am not sure i understand you question since you gave two fixed values to `x`

and `x1`

. If you want to find the limit of the function `some_function = (z -> z*z1)`

when `z`

goes to `z1`

, you can define a symbolic ~~variable ~~function (not to be confused with a python function) :`z`

```
sage: z1 = 3 + 4*I
sage: some_function(z) = z * z1
sage: some_function
z |--> (4*I + 3)*z
sage: some_function.limit(z=z1)
24*I - 7
```
