Calculus Distraught!Long time no see. I am 13 now and am in my second year of university. As you perhaps may not recall, my extremely partial Math teacher has thankfully retired and in my current course work I am facing some tribulations. Apparently my teacher nowadays gets excessively challenging Calculus questions from the Internet. I have discovered a truly marvellous signature, which this margin is too narrow to contain. Fermat Give me a lever long enough and a fulcrum on which to place it, and I shall move the world. Archimedes Young man, in mathematics you don't understand things. You just get used to them.

Re: Calculus Distraught!Hi;
Congratulations! That is very good. Using L' Hospitals rule you will end up with, d(t) > 75 as t > ∞. second question, Annie and the chalk: If you mean as the curve then you are correct. Fourth question, unusual particle: Same as you got. If you are not correct with your answer then at least we will both be wrong. In mathematics, you don't understand things. You just get used to them. I have the result, but I do not yet know how to get it. All physicists, and a good many quite respectable mathematicians are contemptuous about proof. #3 20121007 00:24:45
Re: Calculus Distraught!Well, I have to hand it in by tomorrow so I need to check the other questions as well. Anyways, thanks a lot for the help.

Re: Calculus Distraught!Ummm... Guys... Shouldn't the answer to the first one be the maximum value of d(t)?

Re: Calculus Distraught!
It is, but you would hqve tocprove that too.

Re: Calculus Distraught!You prove it by taking the limit of that function. In mathematics, you don't understand things. You just get used to them.

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

Re: Calculus Distraught!That is very good and true. There is a way to determine where the maximum value is and prove that it occurs at infinity. In mathematics, you don't understand things.

Re: Calculus Distraught!Yes, and that is what is needed to be done in order for the proof to be complete.

Re: Calculus Distraught!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.I have discovered a truly marvellous signature, which this margin is too narrow to contain.

Re: Calculus Distraught!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.

Re: Calculus Distraught!I submitted my results today at Yale and recieved an almostperfect mark.
