Web20 Dec 2016 · Example: Find sin 75°, which is sin 5π/12. Solution: 75° is half of 150°, and you know the functions of 150° exactly because they are the same as the functions of 30°, give or take a minus sign. sin 75° = sin(150°/2) = ±√ (1 − cos 150°)/2. Here, cos 150° is negative because 150° is to the left of the origin, in Quadrant II, and 180° − 150° = 30°, so WebCos is the cosine function, which is one of the basic functions encountered in trigonometry. It is defined for real numbers by letting be a radian angle measured counterclockwise from the axis along the circumference of the unit circle. Cos [x] then gives the horizontal coordinate of the arc endpoint. The equivalent schoolbook definition of the cosine of an …
