Question

    What is the value of 1/(1+tan 2θ ) + 1 / (1+cot 2 θ ) = ?

    A -1 Correct Answer Incorrect Answer
    B 1 Correct Answer Incorrect Answer
    D -2 Correct Answer Incorrect Answer

    Solution

    (1 / 1+ (sin2θ / cos2θ)) + (1/ 1 + (cos2θ/sin2 θ))` (cos2θ/ cos2 θ +sin2θ) + (sin2θ / sin2θ + cos2θ) cos2θ + sin2θ = 1
