**SCALAR TRIPLE PRODUCT**

In terms of expression of rectangular components we can write

(A X B).C = |A_{X} A_{Y} A_{Z}|

|B_{X} B_{Y} B_{Z}

|C_{X} C_{Y} C_{Z}|

In this book when we are taking x, y, z cartesian co-ordinates, we draw x, y, z in anticlockwise sense as per Figures 2.12(a), (b) and (c). This satisfies the requirements of right hand screw rule for vector operations (multiplications of vectors)

But figures 2.12(d), 2.12(e), 2.12(1), will not follow the right hand screw rule and thus discarded for the multiplications of vectors (Here x, y, z are clockwise sense)
