Normally your function can be read explicitly as
and derived immediately to find
Sometimes your function is more difficult to "extricate" and can be difficult to write as
You can only write it as

Consider for example a circle:
As you can see this derivative contains again
In the example of the circle you can write it as (extracting
So that gives you:
It isn't always possible to extract
To test this result try to derive the explicit
