An ellipse is the locus of points in a plane, the sum of whose distances from two fixed points is a constant value. The two fixed points are called the foci of the ellipse.
The general equation of an ellipse is used to algebraically represent an ellipse in the coordinate plane. The equation of an ellipse can be given as, x2a2+y2b2=1x2a2+y2b2=1, where 1. 'a' represents the semi-major axis (half of the length of the major axis) 2. 'b' represents the semi-minor axis (half of the length of the minor axis) Let us go throug...
Perimeter of an ellipse is defined as the total length of its boundary and is expressed in units like cm, m, ft, yd, etc. The perimeter of ellipse can be approximately calculated using the general formulas given as, P ≈ π (a + b) P ≈ π √[ 2 (a2 + b2) ] P ≈ π [ (3/2)(a+b) - √(ab) ] where, 1. a = length of semi-major axis 2. b = length of semi-minor ...
The area of an ellipse is defined as the total area or region covered by the ellipse in two dimensions and is expressed in square units like in2, cm2, m2, yd2, ft2, etc. The area of an ellipse can be calculated with the help of a general formula, given the lengths of the major and minor axis. The area of ellipse formula can be given as, Area of ell...
Eccentricity of an ellise is given as the ratioof the distance of the focus from the center of the ellipse, and the distance of one end of the ellipse from the center of the ellipse Eccentricity of an ellipse formula, e = ca=√1−b2a2ca=1−b2a2
Latus rectum of of an ellipse can be defined as the line drawn perpendicular to the transverse axis of the ellipse and is passing through the foci of the ellipse. The formula to find the length of latus rectum of an ellipse can be given as, L = 2b2/a
The equation of an ellipse formula helps in representing an ellipse in the algebraic form. The formula to find the equation of an ellipse can be given as, Equation of the ellipse with centre at (0,0) : x2/a2 + y2/b2 = 1 Equation of the ellipse with centre at (h,k) : (x-h)2 /a2 + (y-k)2/ b2=1 Example: Find the area of an ellipse whose major and mino...
By placing an ellipse on an x-y graph (with its major axis on the x-axis and minor axis on the y-axis), the equation of the curve is: x 2 a 2 + y 2 b 2 = 1 (similar to the equation of the hyperbola : x 2 /a 2 − y 2 /b 2 = 1 , except for a "+" instead of a "−")
Write equations of ellipses in standard form and graph ellipses. Use properties of ellipses to model and solve real-life problems. Find eccentricities of ellipses. Ellipses can be used to model and solve many types of real-life problems. For instance, in Exercise 59 on page 751, an ellipse is used to model the orbit of Halley’s comet.

a) Find the equation for the ellipse with the centre at (3, 2), passing through the points (8, 2), (-2, 2), (3, -5), and (3, 9). The major axis is parallel to the y-axis and has a length of 14 units, so a = 7. The minor axis is parallel to the x-axis and has a length of 10 units, so b = 5. The centre is at (3, 2), so h = 3 and k = 2. ( x h) 2 b ...
