The question is simple: the domain of f(x, y) = ln( xy−−√ + 1) f ( x, y) = ln ( x y + 1) . Now this is just xy ≥ 0 x y ≥ 0, which means either x ≥ 0 x ≥ 0 and y ≥ 0 y ≥ 0 or y ≤ 0 y ≤ 0 and y ≤ 0 y ≤ 0. This is easy to say and ... calculus. analysis.

$\approx$ is used mostly for the approximate (read: calculated) value of a mathematical expression like $\pi \approx 3.14$ In LaTeX it is coded as \approx. $\cong$ is used to show a congruency between two mathematical expressions, which could be geometrical, topological, and when using modulo arithmetic you can get different numbers that are …A very beautiful introduction to algebraic geometry is the book "Ideals, Varieties, and Algorithms: An Introduction to Computational Algebraic Geometry and Commutative Algebra" in the Springer undergraduate texts in mathematics series.

Technically, the answer is yes. But the painter does much more than that. In fact, it is clear that while the painter must possess quite a large amount of skill in placing paint on canvas, this skill is the least relevant (while absolutely necessary) for the creative process of painting. So it is with mathematics.

$\begingroup$ FYI, you can do something similar to "explain" the Chain Rule: Define a space curve by < f(t), h(t), t > where h(t) = g(f(t)), and (assuming it makes sense) let its tangent vector be < a, b, 1 > (with a != 0).
