How to use Maple to eliminate parameters in surface vector equation to obtain equation in Cartesian coordinates? Help to write the domain in a forma correct way. 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.

If anything, it is going to add to existing confusion people have with the Fourier Series. The sin and cos expression shown is too general to be meaningful, and the graphic shown for the "transform" is really just a visualization of the magnitudes of the …A constant in math is a fixed value.
