engineering mathematics MCQ #476

  1. Question 1

    Q1. The eccentricity of the ellipse x²/a² + y²/b² = 1 (a > b) is

    • A) √(1 - b²/a²)
    • B) √(1 + b²/a²)
    • C) √(a² + b²)/a
    • D) √(a² - b²)/a

    Answer: √(1 - b²/a²)

    Explanation: For the ellipse, b² = a²(1 - e²), so e = √(1 - b²/a²).
