Mathematical Fundamentals

The dot product is commutative i.e., and distributive i.e., . Associative law does not apply to scalar product.
The vector or cross product of two vectors and is denoted by . is a vector perpendicular to the plane containing and , the magnitude is given by and direction is given by right hand rule as explained in Figure 1.5.
