I'm revising over my maths for my exams and I just came across something I didn't understand. How do we know that:
[tex]\frac{d}{dx} \left( e^x \right) = e^x[/tex]
I've seen the infinite series for [itex]e^x[/itex] but in our maths class we derived it by assuming the above statement . Preemptive thanks .
