Hi;

Looks like a typo.

The solution provided by my professor is 1/131, with no direct clarification of the answer.

I submitted my results today at Yale and recieved an almost-perfect mark. Apparently, my answer to the particle question, despite the fact that Bobbym agreed with me, is incorrect.

Yes, I always try to use the username. It is the name the person chose to sign in here so it is obviously there preferred moniker.

Yes. You said so yourself.

Are you sure about that?

bobbym calls everybody by their forum username.

Oh, okay. By the way, you can call me Shivam or Cless. Anyways, I didn't go to Yale today so I will submit  my results later.

Hi Shivamcoder3013;

What anonimnystefy is saying is just because you go to infinity that does not mean you have found a maximum. There is a way to prove have the largest value at 75.

By the way, I apologize for my improper LaTeX syntax.

Well... Using L'Hopitals Rule, we simply take the derivative of the numerator and the denominator separately to get

. Then simply calculate the limit by cancelling the
terms to receive the final answer 75.

Yes, and that is what is needed to be done in order for the proof to be complete.

bobbym

That is very good and true. There is a way to determine where the maximum value is and prove that it occurs at infinity.

anonimnystefy

Not true. That just gets you the limit, but doesn't guarantee that that value is the maximum of the function.

bobbym

You prove it by taking the limit of that function.
