Hey guys, I am quite new to this forum, and just encountered this seemingly simple problem but still was not successful in solving it.
If,
[tex]\frac{x^2}{y^2}+\frac{y^2}{z^2}+\frac{z^2}{x^2}=\frac{x}{y}+\frac{y}{z}+\frac{z}{x}[/tex]
then prove that,
[tex]x=y=z[/tex]
where x,y and z are real numbers.
I tried everything I could from basic identities to substituting x=a+y and x=b+z which one of my friend suggested but no luck yet.
The 'prove that' part seems obvious but I cannot make out how to write a proof.
I have been thinking and trying different ways to solve this for past 3 hours.
I would appreciate if you guys can help me out with this.
