Sine of the difference of two angles (Bhāskara formula)


Trigonometric identities are equalities that involve trigonometric functions and are true for every single value of the occurring variables. Geometrically, these are identities involving certain functions of one or more angles. The sine of the difference of two angles can be calculated by the sine and cosine of the angles.
