Sin A - Sin B is a trigonometric identity for finding angle difference. Formula: Sin A - Sin B = 2 cos ½(A + B) sin ½(A - B). Formula uses compound angles (A + B) and (A - B)
Cone is a three-dimensional object with circular base and tapering apex. Volume of cone is one-third of cylinder volume. Formula: Volume = 1/3 πr²h, where r is radius and h is perpendicular height
