I know that d/dx [e^(x)] = e^(x).

My question:

Why is this the case?

Why is e^(x) its own derivative?

It might help to consider what we actually mean by e^x.

What is the definition of e^x?

1. The hint does not help.

2. Can you explain in MATH FOR DUMMIES style of language?

hi mathland

Somehow I knew in advance that you would want to know about this so I searched back through all my posts and found this:

My last post in the thread was an offer to finish the lessons but only if the guy was interested. I got no response then, but the offer still stands.

Reply on that thread please rather than this one.

Please, finish the lesson. I am interested. This is a lot to digest but not if I divide the reading into 2 or 3 days.
