Your Input

Find the center, foci, vertices, co-vertices, major axis length, semi-major axis length, minor axis length, semi-minor axis length, area, circumference, latera recta, length of the latera recta (focal width), focal parameter, eccentricity, linear eccentricity (focal distance), directrices, x-intercepts, y-intercepts, domain, and range of the ellipse $$$6 x^{2} - 30 \sqrt{2} x + 8 y^{2} - 8 \sqrt{2} y + 67 = 0$$$.

Solution

The equation of an ellipse is $$$\frac{\left(x - h\right)^{2}}{a^{2}} + \frac{\left(y - k\right)^{2}}{b^{2}} = 1$$$, where $$$\left(h, k\right)$$$ is the center, $$$a$$$ and $$$b$$$ are the lengths of the semi-major and the semi-minor axes.

Our ellipse in this form is $$$\frac{\left(x - \frac{5 \sqrt{2}}{2}\right)^{2}}{2} + \frac{\left(y - \frac{\sqrt{2}}{2}\right)^{2}}{\frac{3}{2}} = 1$$$.

Thus, $$$h = \frac{5 \sqrt{2}}{2}$$$, $$$k = \frac{\sqrt{2}}{2}$$$, $$$a = \sqrt{2}$$$, $$$b = \frac{\sqrt{6}}{2}$$$.

The standard form is $$$\frac{\left(x - \frac{5 \sqrt{2}}{2}\right)^{2}}{\left(\sqrt{2}\right)^{2}} + \frac{\left(y - \frac{\sqrt{2}}{2}\right)^{2}}{\left(\frac{\sqrt{6}}{2}\right)^{2}} = 1$$$.

The vertex form is $$$\frac{\left(x - \frac{5 \sqrt{2}}{2}\right)^{2}}{2} + \frac{2 \left(y - \frac{\sqrt{2}}{2}\right)^{2}}{3} = 1$$$.

The general form is $$$6 x^{2} - 30 \sqrt{2} x + 8 y^{2} - 8 \sqrt{2} y + 67 = 0$$$.

The linear eccentricity (focal distance) is $$$c = \sqrt{a^{2} - b^{2}} = \frac{\sqrt{2}}{2}$$$.

The eccentricity is $$$e = \frac{c}{a} = \frac{1}{2}$$$.

The first focus is $$$\left(h - c, k\right) = \left(2 \sqrt{2}, \frac{\sqrt{2}}{2}\right)$$$.

The second focus is $$$\left(h + c, k\right) = \left(3 \sqrt{2}, \frac{\sqrt{2}}{2}\right)$$$.

The first vertex is $$$\left(h - a, k\right) = \left(\frac{3 \sqrt{2}}{2}, \frac{\sqrt{2}}{2}\right)$$$.

The second vertex is $$$\left(h + a, k\right) = \left(\frac{7 \sqrt{2}}{2}, \frac{\sqrt{2}}{2}\right)$$$.

The first co-vertex is $$$\left(h, k - b\right) = \left(\frac{5 \sqrt{2}}{2}, \frac{- \sqrt{6} + \sqrt{2}}{2}\right)$$$.

The second co-vertex is $$$\left(h, k + b\right) = \left(\frac{5 \sqrt{2}}{2}, \frac{\sqrt{2} + \sqrt{6}}{2}\right)$$$.

The length of the major axis is $$$2 a = 2 \sqrt{2}$$$.

The length of the minor axis is $$$2 b = \sqrt{6}$$$.

The area is $$$\pi a b = \sqrt{3} \pi$$$.

The circumference is $$$4 a E\left(\frac{\pi}{2}\middle| e^{2}\right) = 4 \sqrt{2} E\left(\frac{1}{4}\right)$$$.

The focal parameter is the distance between the focus and the directrix: $$$\frac{b^{2}}{c} = \frac{3 \sqrt{2}}{2}$$$.

The latera recta are the lines parallel to the minor axis that pass through the foci.

The first latus rectum is $$$x = 2 \sqrt{2}$$$.

The second latus rectum is $$$x = 3 \sqrt{2}$$$.

The endpoints of the first latus rectum can be found by solving the system $$$\begin{cases} 6 x^{2} - 30 \sqrt{2} x + 8 y^{2} - 8 \sqrt{2} y + 67 = 0 \\ x = 2 \sqrt{2} \end{cases}$$$ (for steps, see system of equations calculator).

The endpoints of the first latus rectum are $$$\left(2 \sqrt{2}, - \frac{\sqrt{2}}{4}\right)$$$, $$$\left(2 \sqrt{2}, \frac{5 \sqrt{2}}{4}\right)$$$.

The endpoints of the second latus rectum can be found by solving the system $$$\begin{cases} 6 x^{2} - 30 \sqrt{2} x + 8 y^{2} - 8 \sqrt{2} y + 67 = 0 \\ x = 3 \sqrt{2} \end{cases}$$$ (for steps, see system of equations calculator).

The endpoints of the second latus rectum are $$$\left(3 \sqrt{2}, - \frac{\sqrt{2}}{4}\right)$$$, $$$\left(3 \sqrt{2}, \frac{5 \sqrt{2}}{4}\right)$$$.

The length of the latera recta (focal width) is $$$\frac{2 b^{2}}{a} = \frac{3 \sqrt{2}}{2}$$$.

The first directrix is $$$x = h - \frac{a^{2}}{c} = \frac{\sqrt{2}}{2}$$$.

The second directrix is $$$x = h + \frac{a^{2}}{c} = \frac{9 \sqrt{2}}{2}$$$.

The x-intercepts can be found by setting $$$y = 0$$$ in the equation and solving for $$$x$$$ (for steps, see intercepts calculator).

x-intercepts: $$$\left(- \frac{2 \sqrt{3}}{3} + \frac{5 \sqrt{2}}{2}, 0\right)$$$, $$$\left(\frac{2 \sqrt{3}}{3} + \frac{5 \sqrt{2}}{2}, 0\right)$$$

The y-intercepts can be found by setting $$$x = 0$$$ in the equation and solving for $$$y$$$: (for steps, see intercepts calculator).

Since there are no real solutions, there are no y-intercepts.

The domain is $$$\left[h - a, h + a\right] = \left[\frac{3 \sqrt{2}}{2}, \frac{7 \sqrt{2}}{2}\right]$$$.

The range is $$$\left[k - b, k + b\right] = \left[\frac{- \sqrt{6} + \sqrt{2}}{2}, \frac{\sqrt{2} + \sqrt{6}}{2}\right]$$$.
