Thanks

Yes, that's correct. In general, we see that $\frac{\,d}{\,dx}\left[ae^x\right]=a\frac{\,d}{\,dx}\left[e^x\right]=ae^x$, where $a$ is a constant.

Hi

The derivative of $2e^x$ is $2e^x$

ever heard of a joke when a guy says to the other:
"I'm gonna derive you like a function!"
And the other one says:
"You can't derive me because im e^x."

:P
