\huge\mathsf{Hoy \ !!}

\large\mathsf{\underline{ \ Given \ : \ }}

\large\mathsf{sin \ [ \ {cot}^{-1} \ \{ \ cos \ ( \ {tan}^{-1} \ ) \ \} \ ]}

\large\mathsf{sin \ [ {\dfrac{1}{cot}} \ \{ \ cos \ ( \ {\dfrac{1}{tan}} \ ) \ \} \ ]}

\large\mathsf{Now,}

\large{\boxed{\mathsf{\red{Using \ some \ formulas}}}}

{\large{\boxed{\mathsf{\red{{\dfrac{1}{cot}} \ = \ tan}}}}}

\large\therefore

\large\mathsf{sin \ [ \ tan \ \{ \ cos \ ( \ {\dfrac{1}{tan}} \ ) \ \} \ ]}

\large\mathsf{sin × tan × cos × {\dfrac{1}{tan}}}

\large\mathsf{sin × {\cancel{tan}} × cos × {\dfrac{1}{{\cancel{tan}}}}}

\large\mathsf{sin × cos}

\large\mathsf\red{sin.cos}
