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. Being a mat educator for over 2 decades, I hope these formulas will equip you to solve problems in vectors
I also take online classes and have short courses on specific topics. A useful video for mathematics students of class 12, ISC, CBSE and STATE.
