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. ...
