Explanation Given: Two ellipses in standard position: E 1 : ( x a 1 ) 2 + ( y b 1 ) 2 = 1 ... ( 1 ) E 2 : ( x a 2 ) 2 + ( y b 2 ) 2 = 1 ... ( 2 ) Calculation: Assume e 1 and e 2 are the eccentricity of the two ellipses and we get: b 1 2 = a 1 2 ( 1 − e 1 2 ) b 2 2 = a 2 2 ( 1 − e 2 2 ) Now, b 2 2 b 1 2 = a 2 2 ( 1 − e 2 2 ) a 1 2 ( 1 − e 1 2 ) If the eccentricity of the two ellipses is equal that means e 1 = e 2 , then the above relation will be: b 2 2 b 1 2 = a 2 2 a 1 2 = r 2 Now, b 2 = r b 1 and a 2 = r a 1 This shows that one ellipse is enlargement of the other ellipse by the factor r...
