In mathematics, a curve (also called a curved line in older texts) is an object similar to a line, but that does not have to be straight. Intuitively, a curve may be thought of as the trace left by a moving point.

For everyday light levels, the photopic luminosity function best approximates the response of the human eye. For low light levels, the response of the human eye changes, and the scotopic curve applies. The photopic curve is the CIE standard curve used in the CIE 1931 color space. WebThe first way is to use a vector with components that are two-variable functions: F(x, y) = 〈P(x, y), Q(x, y)〉. (6.1) The second way is to use the standard unit vectors: F(x, y) = P(x, y)i + Q(x, y)j. (6.2) A vector field is said to be continuous if its component functions are continuous.
