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...

Arc Length

Arc length can be thought of as the distance you would travel if you walked along the path of a curve. Arc length is used in a wide range of real applications. We might be interested in knowing how far a rocket travels if it is launched along a parabolic…

Line Integral

A line integral is one of the important topics that are discussed in the calculus syllabus. When we have a function that we want to integrate, and we evaluate the function alongside a curve, we define it as a line integral. Evaluation of a function along…
