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 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 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.

All the conceptual questions, pure math & basic stats alike I am good at answering your algebra (including logarithm, functions, trigonometry) and geometry questions. I can also provide to you a firm understanding into basic calculus and other mathematical ideas and concepts. You can either ask questions in English or Chinese. Physics Qns that require rigorous math are also welcomed Important:Please avoid asking me questions related to economics.After all, I am only a secondary school student

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 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 see that you recognize that velocity and position are related by a derivative of time, namely, u(t) = dx(t)/dt, and that the solution as a function of time requires must require an integration in
There are two others I know of  e and i. The numbers e is used in the function f(x) = e^x. From this, it can be seen that f'(x) = f(x). The number i = √1. There are some used in physics
Aishwarya, I am not sure what knowledge you are asking for specifically but it looks like you are anxious about your upcoming exams. Here is some advice I got from my abstract algebra professor at Berkeley
Before I answer the question, I will say the units will be in English (and metric). If it feasible? I don't believe so. Water is very dense. A gallon of water weighs 8.34 pounds (3.8 kg). A small
I think the trace of X should be zero. Here's my derivation: Traces have some simple and useful properties, such as (for a matrices A and B) 1. Tr(A +B) = Tr(A) + Tr(B) 2. Tr(A) = Tr(A^t) 3
