Start by showing that After that contemplate its derivative.
You can do this way :
So we have to find the inverse of that.
Let (easier to type )
Then derivate this...
Sorry, my mind is currently completely blank.
Hence doesn't the derivative of

I guess it'd be easier this way

How about using with ?
If you don't know this, it comes from the derivative of .
