I can answer all questions up to, and including, graduate level mathematics. I am more likely to prefer questions beyond the level of calculus. I can answer any questions, from basic elementary number theory like how to prove the first three digits of powers of 2 repeat (they do, with period 100, starting at 8), all the way to advanced mathematics like proving Egorov's theorem or finding phase transitions in random networks. I do not understand why Number Theory is not included in "Advanced Mathematics."

I can answer almost anything that is sent in. If I can't, I'll let you know, but I don't expect that to happen much.

Most questions on number theory, divisibility, primes, Euclidean algorithm, Fermat`s theorem, Wilson`s theorem, factorisation, euclidean algorithm, diophantine equations, Chinese remainder theorem, group theory, congruences, continued fractions. 
First, the quickest way to find information about a sequence is the Online Encyclopedia of Integer Sequences. Using their search form, one can quickly find that your sequence
We can only talk about cross sectional area if it is the same everywhere. i.e. The shape has to be a prism, for example a cuboid, a cylinder, a triangular prism. None of the shapes you give are prisms
Hello Prashant The answer is No. Simple harmonic motion is where the acceleration of a point is proportional to its displacement from a fixed point and in the opposite direction. This gives a second
Hello Kenneth I misunderstood your question. It is the number of gallons that is the dependent variable which is directly proportional to the number of miles and to the number of trips. g = kmt, so
Hello Kenneth I agree with your calculation of k. But miles per gallon was not one of the variables. Clearly if you increase the number of miles per gallon, you decrease gallons per trip, so these are
