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

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.

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 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 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. 
"A length of wire is used to construct two square wire frames." Let the smaller square be x by x inches, and the larger square y by y inches. "The area of one square is onehalf the area of the other
Got it. Using residues will work since the denominator has x raised to a power ≥ 2 than the numerator (so that the contour extending out to ∞ > 0). Fair enough. Your notes indicate that
Thanks for the question. However, your writing is a little too unclear. Attached is an image with what I think is the integral you're working on. I'm a little unsure why you need to use residues since
Put the semicircles together to make a whole circle. Since the width of the circle is the same as the width of the table, radius r = W/2 area of circle = πr² = π(W/2)² = πW²/4 circumference
The rectangular portion is W feet wide and L feet long. area of rectangular portion = WL The semicircles stretch across the width of the table. Combined, they form a circle of radius = W/2. area of
