\underline{\textbf{Given:}}

\mathsf{Cos\,\theta=\dfrac{1}{2}}

\underline{\textbf{To find:}}

\textsf{General solution of}\;\mathsf{Cos\,\theta=\dfrac{1}{2}}

\underline{\textbf{Solution:}}

\mathsf{Consider,}

\mathsf{Cos\,\theta=\dfrac{1}{2}}

\mathsf{Cos\,\theta=cos\,\dfrac{\pi}{3}}

\implies\boxed{\mathsf{\theta=2n\,\pi\,{\pm}\,\dfrac{\pi}{3},\;\;n\,\in\,Z}}

\underline{\textbf{Formula used:}}

\boxed{\begin{minipage}{5cm}$\\\mathsf{If\;co\,\theta=cos\,\alpha,\;\;then}\\\\\mathsf{\theta=2n\,\pi\,{\pm}\,\alpha,\;\;n\;\in\,Z}\\$\end{minipage}}
