en.wikipedia.org/wiki/CIE_1931_color_space

The CIE 1931 color spaces were the first defined quantitative links between distributions of wavelengths in the electromagnetic visible spectrum, and physiological perceived colors in human color vision. The mathematical relationships that define these color spaces are essential tools for color management, important when ...

Jun 28, 2005 **...** Arithmetic and Geometric Means. Date: 11/05/2000 at 15:34:52 From: Rocio
Romero Subject: Lagrange multipliers I have to prove that the geometric mean is
equal to or less than the arithmetic mean for all x, y, and z using Lagrange
multipliers. Geometric mean: G(x,y,z) = (**xyz**)^(**1/3**) Arithmetic mean: A(x,y,z) = (x+
y+z)/3 ...

Suppose we want to find the rate of change of z in the direction of an arbitrary unit vector u = <u1,u2>. Consider the surface S defined by z = f(x, y) and let z0 = f(x0, y0) so that. P = (x0,y0,z0) lies on S. The vertical plane passing through (x0,y0,z0) in the direction of u intersects S in a curve C. The slope of the tangent line to C ...
