About Georgia Martin

A native of Pennsylvania and now a long-time resident of one of the Maryland suburbs of Washington, D.C., Georgia Martin has PhDs in math and physics and is co-author of a book in mathematical logic: Bounded Queries in Recursion Theory. Having worked as a scientist for an agency of the U.S. government for 18 years, she has been self-employed as a document editor since 2000, specializing in math, science, and other technical areas, and has done extensive writing, checking, and editing of solutions to textbook problems. She has also done quite a bit of tutoring in math, and for over 20 years has taught advanced courses in English as a Second Language (ESL) to adults. Georgia has been a BrainMass Expert since 2004, where she always strives to write in a style that will be understandable to students.

Find a self-complementary graph with five vertices.

Let G be a graph. Then G = (V, E), where V and E are the vertex set and edge set, respectively, of G.

The complement of G, which we will refer to as "G bar," is the graph (V, E bar), where V is the vertex set of G bar (i.e., the vertex set of G bar is identical to the vertex set of G) and E bar i READ MORE »

Evaluate the given line integral and the given surface integral.

Do the following:

(1) Evaluate Int(P(x, y) dx + Q(x, y) dy) over the curve C, where P(x, y) = y^2, Q(x, y) = 3x, and C is the portion of the graph of the function y = 3x^2 from (-1, 3) to (2, 12). Here, "Int" stands for integral.

(2) Use the Divergence Theorem to evaluate the surface integral READ MORE »
