Hasse derivative

A Hasse derivative is a special type of mathematical equation that helps us to calculate how much something changes when something else changes. For example, if you have 100 apples and then you add 5 more apples, you can use a Hasse derivative equation to figure out how much the total number of apples changed. It's like a way of measuring the change in something when something else changes.
