engineering mathematics MCQ #478

  1. Question 1

    Q1. The equation of the normal to the parabola y² = 4ax at (at², 2at) is

    • A) y + tx = 2at + at³
    • B) y = tx + 2at + at³
    • C) y - tx = 2at + at³
    • D) y = -tx + 2at + at³

    Answer: y + tx = 2at + at³

    Explanation: The normal to y² = 4ax at (at², 2at) is y + tx = 2at + at³, derived using the slope of the normal.
