प्रतिबंधों को संतुष्ट करते हुए दीर्घवृत्त का समीकरण ज्ञात कीजिए
दीर्घ अक्ष के अंत्य बिंदु $(\pm 3,0),$ लघु अक्ष के अंत्य बिंदु $(0,±2)$
Option A
Option B
Option C
Option D
Solution
Ends of major axis $(±3,\,0)$ , ends of minor axis $(0,\,±2)$
Here, the major axis is along the $x-$ axis.
Therefore, the equation of the ellipse will be of the form $\frac{x^{2}}{a^{2}}+\frac{y^{2}}{b^{2}}=1,$ where a is the semi major axis.
Accordingly, $a=3$ and $b=2$
Thus, the equation of the ellipse is $\frac{x^{2}}{3^{2}}+\frac{y^{2}}{2^{2}}=1$ or $\frac{x^{2}}{9}+\frac{y^{2}}{4}=1$
