Perhaps the following connections between various mathematical concepts will be helpful.
When in doubt, just remember the alphabetical order.

X-coordinate	Y-coordinate
Abscissa	Ordinate
Domain	Range

Cosine	Sine
X-coordinate (of unit circle)	Y-coordinate (of unit circle)
Adjacent / Hypotenuse (in right triangle)	Opposite / Hypotenuse (in right triangle)
