I can answer most questions up through Calculus and some in Number Theory and Abstract Algebra.

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 almost any question from undergraduate mathematics courses.

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 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.

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 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. 
"A rectangular flower bed has a perimeter of 54 feet." Let L and W be the length and width, respectively. L + W = 27 W = 27  L "7 additional beds were placed side by side next to the first bed."
This is more of a chemistry question, but the answer is to add 0.0038 grams per US gallon. Note that 0.0038 grams is 1.3404106e4 ounces. For 30 gallons, this is 0.0040212318 ounces. Basically, you
If sin(2x) = sin(x/2), then 1sinē(2x) = 1sinē(x/2) and cosē(2x) = cosē(x/2) So cos(2x)=cos(x/2) or cos(2x)=cos(x/2) If cos(2x)=cos(x/2) , Sin(3x/2) = sin( 2xx/2 ) = sin(2x)cos(x/2) 
You have to be careful here because you are dealing with infinity, i.e. 1/2 of infinity is still infinity. You are actually asking what the cardinality of the oneoutof10 set is (where 1/10 is the probability
Hi, certainly the probability is NOT zero even though it seems highly unlikely that one would guess correctly. To have a probability of zero it must be an event that could NEVER happen. And since infinity
