y = sin (.5x). The coefficient b in the above graph is 2, so the period of the sine curve changed by a factor of 1/2, making the new period Ï, or about 3.14. y = sin (.5x). For the above graph, the coefficient b = 1/2, so the period of the sine curve will be twice as long as it usually is, or 4 Ï. y = sin (3x).
The term silent revolution refers here to a shift in the prevailing paradigm for international economic and political relations, away from tendencies toward autarky, insularity, mercantilism, and governmental planning and control over economic activity; and toward a common set of beliefs and policies based on open international trade and finance, competitive pricing and production decisions, and cooperation between countries.
A silent film is a film which consists of only the picture, that is, it has no sound. The idea of combining motion pictures with recorded sound is nearly as old as the motion picture itself, but before the 1920s, most films were silent. The years before sound came to the movies are known as the silent era among film scholars and historians.
