FAQs on Equation of Ellipse Video Lecture - Mathematics (Maths) for JEE Main & Advanced

1. How do you find the equation of an ellipse given its foci and major axis length?
Ans. To find the equation of an ellipse given its foci and major axis length, you can use the formula: $c = \sqrt{a^2 - b^2}$, where $c$ is the distance from the center to each focus, $a$ is the length of the major axis, and $b$ is the length of the minor axis. The equation of the ellipse is then $(x-h)^2/a^2 + (y-k)^2/b^2 = 1$, where $(h,k)$ is the center of the ellipse.
2. How do you determine the eccentricity of an ellipse?
Ans. The eccentricity of an ellipse can be determined by the formula $e = c/a$, where $e$ is the eccentricity, $c$ is the distance from the center to each focus, and $a$ is the length of the semi-major axis. The value of $e$ will always be less than 1 for an ellipse.
3. How do you find the equation of an ellipse in standard form given the endpoints of its major and minor axes?
Ans. To find the equation of an ellipse in standard form given the endpoints of its major and minor axes, you can use the formula $(x-h)^2/a^2 + (y-k)^2/b^2 = 1$, where $(h,k)$ is the center of the ellipse, $a$ is the length of the semi-major axis, and $b$ is the length of the semi-minor axis.
4. How do you determine if an ellipse is vertical or horizontal based on its equation?
Ans. If the coefficient of $x^2$ in the equation of an ellipse is larger than the coefficient of $y^2$, then the ellipse is horizontal. If the coefficient of $y^2$ is larger than the coefficient of $x^2$, then the ellipse is vertical.
5. How do you find the foci of an ellipse given its equation in standard form?
Ans. To find the foci of an ellipse given its equation in standard form $(x-h)^2/a^2 + (y-k)^2/b^2 = 1$, you can use the formula $c = \sqrt{a^2 - b^2}$, where $c$ is the distance from the center to each focus. The foci are located at $(h \pm c, k)$.
