Let's consider a code example showing what would be allowed (or not) using different levels of inheritance: 1  class BaseClass {}; void freeStandingFunction(BaseClass* b); class DerivedProtected : protected BaseClass { DerivedProtected() { freeStandingFunction(this); // Allowed } };
Definition of Horizontal Axis. Horizontal means flat or level. Horizontal axis is the x-axis on a graph. The blue number line in the figure below is the x-axis, the horizontal axis.
Best Answer: Horizontal and vertical are simply directions relative to some reference frame. Typically the reference frame in HS and early college physics is Earth's surface.In which case horizontal means parallel to Earth's surface and vertical means perpendicular to Earth's surface.In advanced math and physics, the terms horizontal and vertical will be replaced by unit vectors i, j, and k; where i dot i = 1 etc.nd Ay = A, which means the A vector is pointing straight up the vertical axis. In this case, there is no Ax component. In higher trig you will learn about transformations where we rotate the axes some degrees with the result sometimes of simplifying an otherwise difficult problem.
