    The value of ⁡tan⁡θ+1tan⁡⁡θ\tanθ+\frac1{\tan⁡θ} tanθ+tan⁡θ1​​ is:
    Question

    The value of ⁡tanθ+1tanθ\tanθ+\frac1{\tan⁡θ} ​ is:

    A.

    cosecθcot⁡θ

    B.

    cosθsecθcos⁡θ sec⁡θ ​​

    C.

    cosecθsin⁡θ

    D.

    cosecθsec⁡θ

    Correct option is D

    Given:

    tanθ+1tanθtan\theta+\frac{1}{tan\theta} 

    Formula used:

    tanθ=sinθcosθtan\theta= \frac{sin\theta}{cos\theta} 

    sin2θ+cos2θ=1sin^2\theta+cos^2\theta=1 

    Solution:

    tanθ+1tanθtan\theta+\frac{1}{tan\theta}​​

    sinθcosθ\frac{sin\theta}{cos\theta}+ 1sinθcosθ\frac{1}{\frac{sin\theta}{cos\theta}} = sinθcosθ\frac{sin\theta}{cos\theta}+cosθsinθ\frac{cos\theta}{sin\theta}

    sin2θ+cos2θcosθ×sinθ\frac{sin^2\theta+cos^2\theta}{cos\theta\times sin\theta}= 1cosθ×sinθ\frac{1}{cos\theta\times sin\theta}

    secθcosecθsec\theta cosec\theta

    Thus the correct answer is (D)​​
