I am struggling with whether or not to define the following system as(adsbygoogle = window.adsbygoogle || []).push({}); coupled:

Using LaTeX (reload if it doesn't display properly)

[itex]\ddot{x}+A*x=0[/itex]

[itex]\ddot{y}+A*y=0[/itex]

[itex]\ddot{z}+A*z=0[/itex]

where A is a knownconstantequal to [itex]A=\sqrt{x^2+y^2+z^2}[/itex]

So, what do you think?
