Orthogonal coordinate system

An orthogonal coordinate system is a way to specify points in space using multiple axes that are at right angles (90 degrees) to each other. For example, in a 3D space, the x, y, and z axes are all perpendicular, making it easy to locate any point by measuring how far it is along each axis. This setup simplifies calculations and visualization because the axes do not interfere with one another, providing a clear and organized way to describe positions in space efficiently.
