Why do we call the cosinus cosinus and not sinus?

Isn't the cosinus what comes first? (often on abcissa, and real number axis, exp(ix)=cos(x) and not sin(x)...

And in physics, there are more cos than sin, for example when you compress a spring, you see a cosinus, the spring doesn't move from a deadpoint itself.
We should call the cosinus sinus and the sinus cosinus !

Why do you assume the abcissa is more fundmental then the ordinate?

You really think that "x" is more fundmental then "y" ? They are just labels dipshit. Just because "x" comes before why in the alphebet, doenst mean that thge "object" x point to is more fundmental then the "object" y points to.

Are you 12? 14?

Yes !

If cos is more important, then why is there a sinc function, but not a cosc function?

Checkmate, costards.

We put complex numbers on ordinate, are complex number more fundamental than real? I don't think so, even if it's perfectly subjective, I don't think a lot of people do.

while you're at it, go fix the stupid idea that a positive current is OPPOSITE from the way the electrons move.
