Trigonometric delirium

Mathematics are boring. I'll prove it once more on this page.
Do you see these intincated inequalities?
Don't they look scary? Ugly? Silly? Indeed they are.
And you also will see how stupid nonsense pictures their plotting produces.
Just follow the links below each inequality.

(sin(x)*cos(x)) < sin(sqrt(fabs(x*y)))
Chachi1
(sin(x*x)*cos(y*x)) < sin(sqrt(fabs(x*y)))
Chachi3
(sin(x*y)*cos(x*y)) < sin(sqrt(fabs(x*y)*x*x))
Chachi4
(sin(x*y)*cos(x*y)) < sin(sqrt(y*y*x*x))
Chachi5
Chachi5 zoomed in
(sin(x*y)*cos(x*y)) < sin(sin(x*x)*cos(y*y))
Chachi6
