- 1.1. Show that 
(i) 
∂xi 
∂xj 
= δij and (ii) R = √xixi , 
where R = |R| is the distance from the origin. Hence find ∂R/∂xj in index 
notation. Confirm your result by finding ∂R/∂x in x, y, z notation. 
For an orthogonal co¨ordinate system, 
∂x 
∂y 
= 0 
(this is what is meant by orthogonality) and 
∂x 
∂x 
= 1 . 
In index notation, these results can be combined as 
∂xi 
∂xj 
= δij . 
The distance from the origin is 
R = 
q 
x2 
1 + x2 
2 + x2 
3 = √xixi . 
Combini...
