engineering mathematics MCQ #679

  1. Question 1

    Q1. If y = √(sin(x)), then dy/dx = ?

    • A) cos(x) / (2√(sin(x)))
    • B) cos(x) / √(sin(x))
    • C) sin(x) / √(cos(x))
    • D) √(cos(x))

    Answer: cos(x) / (2√(sin(x)))

    Explanation: Using chain rule, dy/dx = 1/(2√(sin(x))) * d(sin(x))/dx = cos(x) / (2√(sin(x))).
