The curve given by (t-sinh(t)cosh(t), 2 cosh(t)), t real.
It is cosh(x) + c where c is a constant of integration.
Let x = ea then 1/x = e-a where e is the base of natural logarithms. Then y = x + 1/x = ea + e-a So y/2 = (ea + e-a)/2 = cosh(a), the hyperbolic cosine function a = cosh-1(y/2) x= exp(cosh-1(y/2))
It means to follow the regulations such as the law.

It means to be under pressure... A cosh is a small weapon used to beat people with, so if you're under it, you are in danger. "Massively under" would mean way, way under or in a lot of trouble.
If you mean doing graffiti legally, that would be an artist's job.
