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

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 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 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 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'm assuming that the "outside area" is not part of the garden. garden area = 80 yd × W yd = 4,840 yd² W = 60.5 yd dimensions of garden plus outside area: length = 80 + 2×7 = 94 yd width = 60
Numbers began as tic marks on caves where each tic mark represented an item, whether it be a child, a fur or whatever. There is/was a 11 correspondence between the tic mark and the object it referred
Hi AB, The modulus of a complex number z = a + bi is given by the positive value of z = √(a² + b²) So, for x = 2 + 3i x = √(2² + 3²) = √13 which is not the same as 13, and
This looks like a homework problem, but I'll help anyway. The expected value, E(X), is obtained by summing all the values of X and dividing by the total number, N. Adding the same constant value to
Ricardo, Another HW problem (?!). The marginal distribution for x is obtained by summing p(x,y) over y for each value of x. In the table below, I used Excel to do the summing. The rightmost column is
