Let’s say you have a symbolic equation:

```
@syms w x y z
cur_eq = w^2 · x · ( z + 1/2 )
```

How can you work that equation down so you have the following?

```
cur_w_part = w^2
cur_x_part = x
cur_y_part = nothing
cur_eq = ( z + 1/2 )
```

// for this example we assume `z`

will always be caught up in some nonsense.

(i.e. the only separable variables are: `w`

, `x`

, and `y`

)
