CAMP PATRIOT, Kuwait (NNS) -- Naval Coastal Warfare Squadron (NCWRON) 33 from Naval Coastal Warfare Group (NCWGRU) 1 deployed to Kuwait April 14 to relieve NCWRON 25 of NCWGRU 2, which is scheduled to return to Norfolk later this month.
ellipse [(i-lips)] In geometry, a curve traced out by a point that is required to move so that the sum of its distances from two fixed points (called foci) remains constant. If the foci are identical with each other, the ellipse is a circle; if the two foci are distinct from each other, the ellipse looks like a squashed or elongated circle. Note: The orbits of the planets and of many comets are ellipses.
The Ellipses Gizmo starts by relating the formula of an ellipse to the formula of a circle, which is a special type of ellipse. Students then explore the Pythagorean relationship, which allows the position of the foci to be determined. In addition, the Gizmo helps make sense of the definition of an ellipse, which can be a tricky one. An ellipse is a curve created by moving a point so that the sum of its distances from two fixed points (the foci) is constant. Thatâs tough to picture, but the draggable purple point in the Gizmo illustrates it nicely. It also is a perfect lead-in to the hands-on activity of actually drawing an ellipse using a compass, a loop of string, and two push pins.
