Light rays which are reflected by any surface become polarised and polarising filters are used to select which light rays enter your camara lens. They allow you to remove unwanted reflections from non-metallic surfaces such as water, glass etc...
The word linear comes from the Latin word linearis, which means created by lines. In mathematics, a linear map or function f(x) is a function which satisfies the following two properties... Additivity (also called the superposition property): f(x + y) = f(x) + f(y). This says that f is a group homomorphism with respect to addition. Homogeneity of degree 1: f(x) = f(x) for all . It turns out that homogeneity follows from the additivity property in all cases where is rational. (proof) In that case, provided that the function is continuous, it becomes useless to establish the condition of homogeneity as an additional axiom. In this definition, x is not necessarily a real number, but can in general be a member of any vector space. A less restrictive definition of linear function, not coinciding with the definition of linear map, is used in elementary mathematics. The concept of linearity can be extended to linear operators. Important examples of linear operators include the derivative considered as a differential operator, and many constructed from it, such as del and the Laplacian.

Rotating Linear
rotation, which is the linear velocity of a point on the edge of the disk?
radius = 6 if the disk rotates around a central axis, at a speed of 5 rev / s What is the linear velocity of a point on the edge of the disc. I know the answer is 1.9 m / s, but I do not know how to get
The point moves along the circumference of 5 times per second. So that is 2 * pi * radius of 5 times. This is approximately 188.4 m / s. How did you get 1.9? is the radius in centimeters?
