  1. Semi Major Axis

    Linked via "semi-minor axis ($b$)"

    $$PF1 + PF2 = 2a$$
    The semi-major axis/) is thus half of this constant sum. It is the longest radius of the ellipse, extending from the center to the vertices/) (the points farthest apart). Conversely, the shortest radius, the semi-minor axis ($b$)/), extends from the center perpendicular to the major axis to the co-vertices. These two parameters, along with the distance from the [center](/entrie…

  2. Semi Major Axis

    Linked via "semi-minor axis"

    $$a^2 = b^2 + c^2$$
    This relationship implies that for any true ellipse ($eccentricity ($e$) > 0$), the semi-major axis/) must always be greater than both the semi-minor axis/) and the focal distance ($a > b$ and $a > c$).
