# Coordinate System FAQs:

Q: Is a coordinate system a system which uses one or more numbers?

A: Yes, or coordinates, to uniquely determine the position of the points or other geometric elements on a manifold such as Euclidean space.

Q: Is a coordinate system held constant and the other coordinate is allowed to vary?

A: Yes, and then the resulting curve is called a coordinate curve.

Q: Is a coordinate system the Cartesian coordinate system?

A: Yes.

Q: Is a coordinate system called curvilinear coordinate systems?

A: Yes.

Q: Are coordinate systems used not only to describe the position of points?

A: Yes, but also to describe the angular position of axes, planes, and rigid bodies.

Q: Is a coordinate system one where only the ratios of the coordinates are significant and not the actual values?

A: Yes.

Q: Is a coordinate system the identification of points on a line with real numbers using the number line?

A: Yes.

Q: Is a coordinate system the spheres with center at the origin?

A: Yes.
