Question

# In Q. No. 9, what is the value of $\frac{{a}^{2}}{bc}+\frac{{b}^{2}}{ca}+\frac{{c}^{2}}{ab}$?

Solution

## The co-ordinates of the vertices are (a, b); (b, c) and (c, a) The co-ordinate of the centroid is (0, 0) We know that the co-ordinates of the centroid of a triangle whose vertices are is- So, Compare individual terms on both the sides- Therefore, We have to find the value of - Multiply and divide it by to get, Now as we know that if, Then, So, MathematicsRD Sharma (2014)Standard X
