Prove the law of sine using a cross product

1.	Prove the law of sine using a cross product
Answer» Answer: Sine law can be proved by using Cross products in Vector Algebra. Cross product between TWO VECTORS is the AREA of a PARALLELOGRAM formed by the two vectors as the sides of the parallelogram. ... On taking the RECIPROCAL of this, a / Sin A = b / Sin B = c / Sin C. This is the Sine law.
