i) The x coordinate of the centroid is given by: (1/A)∫{x*f(x)}dx in [x = a to b] 

ii) And y coordinated of the centroid is given by: (1/A)∫[f(x)]² dx in [x = a to b] 

iii) And A is the area which is given by ∫f(x) dx in [x =a to b] 

iv) Here, f(x) = 1/x; a = 1 and b = 2 

Substituting these and evaluating we get the coordinates as: ( 1/ln|2|, 1/4ln|2| )
