Conic section

She had to use the Greek lettering system to solve math problems and correct equations, due to the Arabic numerical system not being introduced at the time. Most of Hypatia’s known mathematics were conducted by using the formulas of x-y=a and x^2-y^2=(x-y) +b, which were referred to as simultaneous pairs. Most of her well known contributions to math were revisions to the work of her male cohorts. Three of her heavily appraised corrections and commentaries were to that of: Ptolemy’s “Almagest”, Apollonius’ review of Conics, and her father Theon’s lessons of the “Euclid Elements”. She even revised her commentary of “The Arithmetica” conducted by…

Degenerate Cases of Conic Sections: Conics are formed when a plane and a double cone intersect. These intersections can form a variety of conics. These include: circles, parabolas, ellipses and hyperbolas. A circle can be formed from a cone if a plane intersects with the cone at an angle perpendicular to the base of the cone. This circle is also formed by the equation: (x-h)2+ (y-k)2=r2. This equation creates a relation because the collection of points does not pass the vertical line test. To…

What does the text say? A Sand County Almanac is a book comprised of a few essays for each month of the year. • JULY - Great Possessions describes the array of birds and animals that can be seen at the farm before dawn as more precious “possessions” than the Leopold’s “worldly domain”. Prairie Birthday is about the small flower with strong, deep roots called Silphium. • AUGUST - The Green Pasture depicts the silt ribbon on a river shore and its lush, temporary vegetation as an “evanescent…

While reading “The Osage Firebird,” I saw how the structure of the text, led to one another. Meaning, when the author, Sudipta Bardhan, wrote this passage she made it connect really well to each other. While reading the passage, I observed how she did it. She did it by adding one detail in one section, then that one detail becomes the main idea for the next section, or for any section. I saw the connection of each section near the end, since in the beginning of the passage, I didn’t see any. …

Mid Fall 2012 The plane ride here was a long one. The droning engines of the C-17 went on for hours and pierced through my earplugs. I could only feel overwhelmed and excited by what was happening. I was finally getting sent overseas after four long years of basic training. A few nervous thoughts had passed my mind about what could happen, but was soon drowned out by the engines. The passenger section of the C-17 was nothing like a civilian aircraft. A few rows of seats with our gear packed in…

What was interesting about this piece was the opening and closing vamping sections which allowed for some more room to improvise other than the sections in the middle. The opening vamp featured the electric bass as the driving force improvising on two main elements of walking bass lines and this riff idea that would emerge in the head, and underneath this the electric keyboard played a sparse chordal accompaniment along with the drummer playing a light rock-shuffle groove. The main sections of…
