Question
If a = b in the equation of ellipse x²/a² + y²/b² =
1, then the curve becomes:Solution
We are given the standard equation of an ellipse: x²/a² + y²/b² = 1 Now, if a = b, then the equation becomes: x²/a² + y²/a² = 1 ⇒ (x² + y²)/a² = 1 ⇒ x² + y² = a² This is the standard equation of a circle centered at the origin with radius a.
