Some real-life examples of conic sections are the Tycho Brahe Planetarium in Copenhagen, which reveals an ellipse in cross-section, and the fountains of the Bellagio Hotel in Las Vegas, which comprise a parabolic chorus line, according to Jill Britton, a mathematics instructor at Camosun College. The conics curves include the ellipse, parabola and hyperbola.Continue Reading
The ellipse is the most common conic curve frequently seen in everyday life because each circle appears elliptical when viewed obliquely, states Britton. For example, the surface of water in a glass obtains an elliptical outline when the glass is tilted. Salami is usually cut obliquely to acquire elliptical slices. The orbits of the earth's artificial satellites and the moon are elliptical as well as the paths of comets that permanently orbit the sun. Another elliptic structure is the Statuary Hall in the U.S. Capital building. An elliptical billiard table demonstrates the ability of the ellipse to rebound an object beginning from one focus to another, causing a ball to rebound to the other focus when positioned at a certain focus and thrust with a cue stick.
A real-life example of a parabola is a baseball being hit into the air and following a parabolic path, explains Britton. The center of gravity of a jumping porpoise also describes a parabola.Learn more about Measurements
A ladder placed against a building is a real life example of a linear pair. Two angles are considered a linear pair if each of the angles are adjacent to one another and these two unshared rays form a line. The ladder would form one line, while a building or wall would form another line.Full Answer >
The most common series circuit in everyday life is the light switch. A series circuit is a loop that is completed with a switch connection sending electricity through the loop.Full Answer >
Converting degrees Celsius into degrees Fahrenheit is an essential skill to have when working in the fields of science or mathematics. To convert degrees Celsius to degrees Fahrenheit, multiply the degrees Celsius by 180/100 and then add 32.Full Answer >
A radian is a unit of angular measure widely used in many branches of mathematics and physics. One radian is equal to the measure of an angle at the center of a circle with an arc that is equal in length to the radius of that circle. Since the perimeter of a circle is found by doubling the radius and multiplying by pi, one radian is equal to 180 degrees divided by pi, or roughly 57.2958 degrees.Full Answer >
