The comments of Habrus burn again:
In wartime, the cosinus angle can reach four. If very necessary.

Not a cosinus, but a pi.
Excuse me

And now imagine that even cosinus in wartime can get somewhere equal to 4. It is a disaster!

In wartime, the sinus angle can be blue. If the boss ordered.

Judging by trends, in our time the sinus of the angle can be condemned if it is not blue.
