$\dfrac{2014a^2+b^2+c^2}{a^2}=\dfrac{a^2+2014b^2+c^2}{b^2}=\dfrac{2^2+b^2+2014c^2}{c^2}$
$=>2014+\dfrac{b^2+c^2}{a^2}=2014+\dfrac{a^2+c^2}{b^2}=2014+\dfrac{a^2+b^2}{c^2}$
$=>\dfrac{b^2+c^2}{a^2}=\dfrac{a^2+c^2}{b^2}=\dfrac{a^2+b^2}{c^2}$
$=>\dfrac{b^2+c^2+a^2+c^2+a^2+b^2}{a^2+b^2+c^2}=\dfrac{2(a^2+b^2+c^2)}{a^2+b^2+c^2}=2$
$=>\dfrac{b^2}{a^2}+\dfrac{c^2}{a^2}=\dfrac{a^2}{b^2}+\dfrac{c^2}{b^2}=\dfrac{a^2}{c^2}+\dfrac{b^2}{c^2}=2$
$=>\dfrac{b^2}{a^2}+\dfrac{c^2}{a^2}+\dfrac{a^2}{b^2}+\dfrac{c^2}{b^2}+\dfrac{a^2}{c^2}+\dfrac{b^2}{c^2}=6$
$=>\dfrac{b^2}{a^2}+\dfrac{c^2}{a^2}+\dfrac{c^2}{b^2}=3$
