Arre, standard equation hai na, \( \frac{x^2}{25} + \frac{y^2}{9} = 1 \) toh \( a^2 = 25, b^2 = 9 \). Eccentricity \( e = \sqrt{1 - \frac{b^2}{a^2}} = \sqrt{1 - \frac{9}{25}} = \frac{4}{5} \). Foci (±ae, 0) honge, yani (±4, 0). Par bhai, ye formula toh rat liya maine, lekin samajh aaya nahi pura... kya ye foci koi fixed points jaise Mummy ka salon tha, jahan sab log aate the? Mujhe lagta hai maths ke liye bhi ek 'center' chahiye hota hai, warna sab kuch bikharta hai, jaise ab Mummy ke bina salon chalana.
