How do we go about this?
Consider vector X=Xii. The magnitude of vector X is a scalar M such that M2=(X1)2+(X2)2+(X3)2 Demonstrate that: M=Xi/M Hint: You can start taking the derivative of M respect of one of the directions. You only need to work with one direction since it will be a similar procedure for each one of the coordinate directions
