I can provide good answers to questions dealing in almost all of mathematics especially from A`Level downwards. I can as well help a good deal in Physics with most emphasis directed towards mechanics.  
Paul KlarreichAvailable

I can answer questions in basic to advanced algebra (theory of equations, complex numbers), precalculus (functions, graphs, exponential, logarithmic, and trigonometric functions and identities), basic probability, and finite mathematics, including mathematical induction. I can also try (but not guarantee) to answer questions on Abstract Algebra  groups, rings, etc. and Analysis  sequences, limits, continuity. I won't understand specialized engineering or business jargon.

I can answer any questions from the standard four semester Calulus sequence. Derivatives, partial derivatives, chain rule, single and multiple integrals, change of variable, sequences and series, vector integration (Green`s Theorem, Stokes, and Gauss) and applications. PreCalculus, Linear Algebra and Finite Math questions are also welcome.

I can answer any question in general math, arithetic, discret math, algebra, box problems, geometry, filling a tank with water, trigonometry, precalculus, linear algebra, complex mathematics, probability, statistics, and most of anything else that relates to math. I can also say that I broke 5 minutes for a mile, which is over 12 mph, but is that relevant?

I can answer questions in Algebra, Basic Math, Calculus, Differential Equations, Geometry, Number Theory, and Word Problems. I would not feel comfortable answering questions in Probability and Statistics or Topology because I have not studied these in depth.

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 can answer most questions up through Calculus and some in Number Theory and Abstract Algebra. 
Hi Kenneth, Yes, the inverse relationship means that you can't divide in that sense. In this case, the number of pipes multiplied by the time it takes to drain the tank is a constant, assuming pipes of
Hi, The variable you are curious about is actually a function, namely the natural logarithm. It is written as "ln", or "el en" (for "log natural", I suppose). The log function tells you the exponent
This problem is a good example of how to use contour integration and various theorems on Fourier Transforms to calculate the integral (which makes it worthwhile even though this looks like a homework problem)
It means neither one determines the other. If you are told one , you can't figure out the other. For example , a person's height and age are independent variables. If I tell you that a man is 30 years
Hi, you want to make one of the variables disappear, that means you need to find a multiple of either A or B so that one is negative and one is positive. Try 4 times the 1st equation and 19 times the
