hi all :) got my re-exam for math tomorrow and i was wondering what the answer is to this:
whats the derivitive of e^a (a is an element of R)

Very good admin
03:16 +Thomm • just for the curiosity?
as long as e=euler number atleast
cause its like f'(x) of e^a where e = 2;8 and a is random number (like -1,2,3) makes it like 2,8^4 and without an x this is just a constant which results in being 0
e is just 2,8 and even if you do ^ANY NUMBER it will still but a random number (=C)
and f'(x) of c = 0
i forgot how you can prove it, but its an exception of the other "e^..." syntax where you dont need to apply the chain rule or product rule or whatever its called...but its only in this special case... for example in the case e^2x or e^-x you have to apply the rules again
normally you couldnt just do like y=2.8^2 =>y=7,84 => y'=0
you have to apply rules first to be allowed to derive it
and when you substitute a value and derive, you get a different value as when you applied the rules first and derived then

hf searching in there :D
tog merci ;)
np :)
f(a) = e^a
then f'(a) = e^a
if (a) is just a random number of R, then the function looks like:
f(x) = e^a
and f'(x) = 0
already figured it out but thx anyway
got exam in 1,5h
