In geometry, an ellipse is a closed curve where the sum of the distances from any point on the curve to two fixed points (the foci) is a constant. The latus rectum is a line segment that passes through one focus of an ellipse and is perpendicular to the ellipse's directrix. In this...
Ellipse - Get an introduction to the topic of an ellipse and learn about the ellipse formula along with some important equations of ellipse like the tangent equation, chord equation and more.
An ellipse is a geometric shape that is generated when a plane intersects a conical shape and produces a closed curve. Circles are a special subset of the ellipse. Though any particular formula for these shapes may seem rather complex, they are a common form in natural systems such as in o...
For a taller-than-wide ellipse with center at (h, k), having vertices a units above and below the center and foci c units above and below the center, the ellipse equation is: An ellipse equation, in conics form, is always "=1". Note that, in both equations above, the h always st...
And how do we find these foci? Let’s focus(!) on the last question first. Recall that an ellipse is a stretched circle. In other words, an ellipse is what forms when you slice a tall, circular tube (cylinder) along a slant: ...

What is vertical displacement? How do you write an equation of a line that is parallel to another line that passes through a point? Find the equation of the ellipse given: 1) Foci (0, \pm 5) 2) Vertices (0, \pm 8) What is the sine rule? How can you find the graph of an equ...
Find the equation of the ellipse given: 1) Foci (0, \pm 5) 2) Vertices (0, \pm 8) Assume that a piece of bamboo is a hollow cylinder of negligible wall thickness. What is the numerical value (in cm) of ratio of volume to surface area of such a cylinder having a diameter of ...
The one-sheeted hyperboloid isa surface of revolution obtained by rotating a hyperbola about the perpendicular bisector to the line between the foci(Hilbert and Cohn-Vossen 1991, p. 11). A hyperboloid of one sheet is also obtained as the envelope of a cube rotated about a space diagonal (...
Find the equation of the ellipse given: 1) Foci (0, \pm 5) 2) Vertices (0, \pm 8) How do you graph a piecewise function? What is component form in the context of vectors? How do you to convert polar to rectangular coordinates?
