Lagrange Series Reversion

Obsolete ? Certainly not in Industrial Control Systems. They are based on maths that work with much less risk of failure than the CAS., based on the latest microprocessors too. So, here are the two forms:

1. if you have the function in the series directly or converted to,

2. if you have the function in the native polynomial form.

As is, not checked from my file, present it better !
