Hi. I was just wondering, how can i prove the following identity:(adsbygoogle = window.adsbygoogle || []).push({});

[tex]

\frac{{dy}}{{dx}}\frac{{dx}}{{dy}} = 1

[/tex]

Its nothing that im required to know, but i was just curious, so for all i know, it may be way out of anything that i can mathematically comprehend.

The best ive been able to do is show that it holds true for some examples that ive tried, but no solid proof.

Thanks in adavnce,

Dan.
