base. The cone did not have to be a right cone‚ but could be slanted‚ or oblique. Apollonius noticed that all sections cut through such a cone parallel to its base were circles. He then extended the properties that he observed from these circles to ellipses and the other conic sections. He even solved the difficult problem of finding the shortest and longest distances from a given point to a conic section. These distances lie on lines called normals‚ which cut the curve of a conic section at right angles

P.O.W. #4 Pockets of Pool Problem Statement For this POW imagine a modified pool table in which the only pockets are those in the four corners. This POW will use a “bird’s eye view” or looking at the table from above all the time‚ with different parts and shapes of the table labeled. Next‚ imagine that the ball is hit from the lower left‚ in a diagonal direction that forms a 45 degree angle. Finally‚ let’s say that every time the ball hits a side of the table‚ it bounces off in a 45 degree angle

[edit] Mathematics [edit] Pi as irrational Aryabhata worked on the approximation for Pi (π)‚ and may have come to the conclusion that π is irrational. In the second part of the Aryabhatiyam (gaṇitapāda 10)‚ he writes: caturadhikam śatamaṣṭaguṇam dvāṣaṣṭistathā sahasrāṇām ayutadvayaviṣkambhasyāsanno vṛttapariṇāhaḥ. "Add four to 100‚ multiply by eight‚ and then add 62‚000. By this rule the circumference of a circle with a diameter of 20‚000 can be approached."[12] This implies that the

Keplar’s First Law of Planetary Motion: The orbit of every planet is an ellipse with the sun at one of the foci. The purpose of this lab is to demonstrate Keplar’s First Law of Planetary Motion by calculating the eccentricity of ellipses. The 3 main words that were important in this lab exercise was eccentricity‚ ellipse‚ and foci. Eccentricity means the degree of ovalness of an ellipse or how far an ellipse is from being a circle. Ellipse is a closed curve around two points in which the sum of the distances

a circle‚ an ellipse‚ a parabola‚ or a hyperbola. The term "Conic Section" can be applied to any one of these curves‚ and the study of one curve is not essential to the study of another. However‚ their correlation to each other is one of the more intriguing coincidences of mathematics. A CONIC SECTION DEFINITION Put simply‚ a conic section is a shape generated when a cone intersects with a plane. There are four main types of conic sections: parabola‚ hyperbola‚ circle‚ and ellipse. The circle

Translated chapters from the book of Fukagawa and Pedoe were devoted to ellipses and n-gons‚ different combinations of the ellipses‚ circumferences and quadrilaterals‚ spheres‚ spheres and ellipsoids‚ different combination of the spheres and n-gons. In this science project the most interesting and original solutions of geometric problems were considered
