WebbEarly in the 17th century, the German astronomer Johannes Kepler applied the ellipse to the description of planetary orbits, and the Italian scientist Galileo Galilei employed the parabola to describe projectile motion in the absence of air resistance. In mathematics, a parabola is a plane curve which is mirror-symmetrical and is approximately U-shaped. It fits several superficially different mathematical descriptions, which can all be proved to define exactly the same curves. One description of a parabola involves a point (the focus) and a line … Visa mer The earliest known work on conic sections was by Menaechmus in the 4th century BC. He discovered a way to solve the problem of doubling the cube using parabolas. (The solution, however, does not meet the requirements of Visa mer The previous section shows that any parabola with the origin as vertex and the y axis as axis of symmetry can be considered as the … Visa mer Two objects in the Euclidean plane are similar if one can be transformed to the other by a similarity, that is, an arbitrary composition of … Visa mer The reflective property states that if a parabola can reflect light, then light that enters it travelling parallel to the axis of symmetry is reflected toward the focus. This is derived from geometrical optics, based on the assumption that light travels in rays. Visa mer Axis of symmetry parallel to the y axis If one introduces Cartesian coordinates, such that $${\displaystyle F=(0,f),\ f>0,}$$ and the directrix has the equation $${\displaystyle y=-f}$$, one obtains for a point $${\displaystyle P=(x,y)}$$ from Visa mer Diagram, description, and definitions The diagram represents a cone with its axis AV. The point A is its apex. An inclined cross-section of … Visa mer A parabola can be considered as the affine part of a non-degenerated projective conic with a point $${\displaystyle Y_{\infty }}$$ on the line of infinity $${\displaystyle g_{\infty }}$$, which is the tangent at $${\displaystyle Y_{\infty }}$$. The 5-, 4- and 3- point … Visa mer
