hello friend in my openion you are wrong in frist question

Comments like that are kind of confusing. Can you be more specific. We both have names which will help to differentiate us from each other.

Do you mean me or 123ronnie321. Please use the usernames.

Sorry, opinions have little weight in mathematics. Just saying someone is wrong is adversarial and unproductive.

You must back up your claims. Can you prove your statement?

What you probably did wrong was you forgot to divide by 3.

Where 1,w1 and w2 are the roots of unity.

Same answer as I got. But that is not how I did it.

]]>i tried condensing those series and i got the result very similar to what you posted. I must have made some silly error while calculating.

i wrote the series of e^x, e^wx & e^(w^2)x {where w = complex cube root of unity} and added the three......

f` = g

g`= h

h`= f

f,g,h are different functions.

where f means f(x) and f` means f`(x)

A simpler version -

f` = g

g`= f

f(0) = 1

g(0) = 0

find f(1)
