\textbf{Given:}

\mathsf{2\;cos^2\theta(1+tan^2\theta)}

\textbf{To find:}

\textsf{The value of}\;\mathsf{2\;cos^2\theta(1+tan^2\theta)}

\textbf{Solution:}

\textsf{Consider,}

\mathsf{2\;cos^2\theta(1+tan^2\theta)}

\mathsf{Using,}\;\boxed{\mathsf{sec^2A=1+tan^2A}}

\mathsf{=2\;cos^2\theta(sec^2\theta)}

\mathsf{=2\;cos^2\theta{\times}\dfrac{1}{cos^2\theta}}

\mathsf{=2}

\implies\boxed{\mathsf{2\;cos^2\theta(1+tan^2\theta)=2}}

\textbf{Find more:}

If 6 sin²θ + 2 cos²θ=7 sinθcosθ then find the value of tan θ. Class 10
