you've heard of sine and cosine

now get ready for uh squine and cosquare

@acegikmo very peculiar (though it took me a while to catch it because the color choice for the plots isn't too colorblind-friendly).

I'm trying to think if they satisfy an equation similar to that of sin/cos, but abs(s) + abs(c) = 1 doesn't work. Is it something like abs(s+c) + abs(s-c) = 1 maybe?

@oblomov @acegikmo max(abs(s), abs(c)) = 1?
@ziks @acegikmo well I was at least missing a /2, and max(x,y) = (x+y+abs(x-y))/2 so maybe mine should have been abs(x)+abs(y)+abs(x-y) = 2
