    Simplify: (sin²θ/cos θ) + (cos²θ/cos θ)
    Question

    Simplify: (sin²θ/cos θ) + (cos²θ/cos θ)

    A.

    cot θ

    B.

    sec θ

    C.

    tan θ

    D.

    cosec θ

    Correct option is B

    Given:

    The expression is sin2θcosθ+cos2θcosθ\frac{\sin^2 \theta}{\cos \theta} + \frac{\cos^2 \theta}{\cos \theta}​​

    Formula Used:
    Using the identity sin2θ+cos2θ=1\sin^2 \theta + \cos^2 \theta = 1​​

    Solution:
    Combine the terms over the common denominator cosθ\cos \theta​ :

    sin2θcosθ+cos2θcosθ=sin2θ+cos2θcosθ\frac{\sin^2 \theta}{\cos \theta} + \frac{\cos^2 \theta}{\cos \theta} = \frac{\sin^2 \theta + \cos^2 \theta}{\cos \theta}​​

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

    1cosθ\frac{1}{\cos \theta}​​

    secθ\sec \theta​​

    Therefore, the simplified expression is secθ\sec \theta​ .
