Full Screen The sine of an angle φ greater than 90 0 is defined as
ordinate of point M ημφ = distance of point M from 0
If we consider that point Μ performs a smooth circular movement with a constant angular speed ω then the angle φ which is formed by radius ΟΜ will be the following :
Therefore
In other words , the projection of point Μ on the axis y ’ y ( ordinate ) performs a simple harmonic oscillation of a width equal to the radius of the cyclical orbit and angular frequency equal to the angular speed of the circular movement .
We then posted the web page link to Edmodo , ( http :// www . seilias . gr / index . php ? option = com _ content & task = view & id = 313 & Itemid = 55 ) so that the students could enter from home , study it and enhance their understanding . We also follow this procedure with other chapters of 3 rd Lyceum Physics such as on Waves and Electromagnetism . For more information , you may also visit this web page .
