\textbf{To find:}

\textsf{The value of}

\mathsf{2\;sin^2A+2\;cos^2A}

\textbf{Solution:}

\textsf{Consider,}

\mathsf{2\;sin^2A+2\;cos^2A}

\textsf{By taking 2 as common,}

\mathsf{=2(sin^2A+2\;cos^2A)}

\mathsf{Using,}

\boxed{\mathsf{Sin^2\theta+cos^2\theta=1}}

\mathsf{=2(1)}

\mathsf{=2}

\implies\boxed{\mathsf{2\;sin^2A+2\;cos^2A=2}}

\textbf{Find more:}
