Hey everyone
So I had my first claculus test today and it was, well...hard! I just don't understand differentiation by first principles. I've tried various methods but it's just not making any sense to me. Does anyone know how to explain the concept in a fairly simple way that's easy to understand.
Any help would be much appreciated
Thanks
