engineering mathematics MCQ #1845

  1. Question 1

    Q1. The eccentricity of the ellipse x² / 4 + y² / 9 = 1 is

    • A) √5 / 3
    • B) √5 / 2
    • C) 2 / 3
    • D) 3 / 2

    Answer: √5 / 3

    Explanation: For the ellipse x² / b² + y² / a² = 1, where a > b, eccentricity e = √(1 - b² / a²) = √(1 - 4 / 9) = √(5 / 9) = √5 / 3
