VECTORS-FORMULAS FOR CLASS 12 MATHEMATICS

Presenting a set of formulas for class 12 Mathematics-Vectors. This is a quick revision for you when you are preparing for your exams. I start with a simple representation of vectors, projection of one vector on another. Then we have dot product, cross product and move on to formulas on scalar triple product and its applications. Lagrange's identity connecting dot product with scalar product is also mentioned.
