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.
The standard equation of an ellipse with a horizontal major axis is the following: + = 1 . The center is at (h, k) . The length of the major axis is 2a , and the length of the minor axis is 2b . The distance between the center and either focus is c , where c 2 = a 2 - b 2 . Here a > b > 0 .
