WebDec 20, 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 WebDec 2, 2016 · To find out the value of 2"B" in the third quadrant, do 360-cos(2"B").
