Ellipse Sign 588
In mathematics, an ellipse is a plane curve surrounding two focal points, such that for all points on the curve, the sum of the two distances to the focal points is a constant. It generalizes a circle, which is the special type of ellipse in which the two focal points are the same. The elongation of an ellipse is measured by its eccentricity e, a number ranging from e = 0 (the limiting case of a circle) to e = 1 (the limiting case of infinite elongation, no longer an ellipse but a parabola). An ellipse has a simple algebraic solution for its area, but only approximations for its perimeter (also known as circumference), for which integration is required to obtain an exact solution. Analytically, the equation of a standard ellipse centered at the origin with width 2a and height 2b is: : \frac+\frac = 1 . Assuming a \ge b, the foci are (\pm c, 0) for c = \sqrt. The standard parametric equation is: : (x,y) = (a\cos(t),b\sin(t)) \quad \text \quad 0\leq t\leq 2\pi. Ellipses are ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Puerto Rico Highway 588
Puerto Rico Highway 588 (PR-588) is a tertiary mountainous state highway in Ponce, Puerto Rico. The road is approximately 1.5 kilometers long and is a spur of Puerto Rico Highway 504. Route description At its southern terminus, the road starts at coordinates in its intersection with Puerto Rico Highway PR-504, and terminates at its northern terminus at coordinates at its intersection with Camino La Zarza. The road runs north to south, and mostly along Río Chiquito in barrio Portugués. The southern terminus connects at kilometer mark 3.0 of PR-504. Its northern terminus connects with Camino La Zarza, which leads eastwardly back to PR-504 via Camino Río Chiquito Hoyos, which becomes Camino La Cuchilla in its approach to PR-504. This Camino Río Chiquito Hoyos/Camino La Cuchilla run is about 0.9 kilometers long. Major intersections Letrero en PR-504, km 3.4, viajando al sur, anunciando intersección con PR-588, Bo.
