The parabolic curve is therefore the locus of points where the equation is satisfied, ... and V is the principal vertex of the parabola VG. Draw VX perpendicular to SV.
While a parabolic arch may resemble a catenary arch, a parabola is a quadratic function while a catenary is the hyperbolic cosine, cosh(x), a sum of two exponential functions. One parabola is f(x) = x 2 + 3x − 1, and hyperbolic cosine is cosh(x) = e x + e −x / 2 . The curves are unrelated.
Two-dimensional parabolic coordinates (,) are defined by the equations, in terms of Cartesian coordinates: = = The curves of constant form confocal parabolae = that open upwards (i.e., towards +), whereas the curves of constant form confocal parabolae
A conic section, conic or a quadratic curve is a curve obtained from a cone's surface intersecting a plane. The three types of conic section are the hyperbola , the parabola , and the ellipse ; the circle is a special case of the ellipse, though it was sometimes called as a fourth type.

If there are mixed with distributed loads and concentrated, the moment diagram (M/EI) will results parabolic curves, cubic, etc. Then, assume and draw the deflection shape of the structure by looking at M/EI diagram. Find the rotations, change of slopes and deflections of the structure by using the geometric mathematics.
A quadratic Bézier curve is also a segment of a parabola. As a parabola is a conic section, some sources refer to quadratic Béziers as "conic arcs". [12] With reference to the figure on the right, the important features of the parabola can be derived as follows: [13] Tangents to the parabola at the endpoints of the curve (A and B) intersect ...
A parabolic segment is the region bounded by a parabola and line. To find the area of a parabolic segment, Archimedes considers a certain inscribed triangle. The base of this triangle is the given chord of the parabola, and the third vertex is the point on the parabola such that the tangent to the parabola at that point is parallel to the chord.
