Deriving the sine or cosine of an arbitrary angle takes a bit more math than is covered here. ... Note first of all that a right-angled triangle contains two angles. ... Because the side opposite to A is the one adjacent to (90њ- A), it follows that the sine of one angle is the cosine of the other, and vice versa: . ... Consider the triangle PQR (drawing) with all three angles equal to 60њ. ... If we want the angle A to grow in equal steps of 15 o , we still need the sine and cosine of 15њ and 75њ. ...

... Following a flare on 9 July '96, a solar quake on the solar surface was observed for the first time. It contained 40,000 times the energy released in the great earthquake that devastated San Francisco in 1906. In an hour, the waves traveled a distance ten times that of the Earth's diameter. The waves accelerated from 22,000 miles per hour to 250,000 miles per hour as they travelled outwards and disappeared into the photosphere. A solar-quake following a large flare . ...
