$\large\color {orange}\sf {\implies To \: Find :}$



$\large\color {purple}\sf {The \: maximum \: value \: of \: {\dfrac {1}{sec \: è}}}$



$\large\color {green}\sf {\implies We \: know \: that : }$



$\large\color {violet}\sf {- 1 \leqslant cos \: è \leqslant 1}$



$\large\color {blue}\sf {Thus, the \: maximum \: value \: of \: cos \: è \: is \: 1}$



$\large\color{purple}\sf {cos \: è = {\dfrac {1}{sec \: è}}}$




$\large{ \boxed{ \boxed{ \red{ \sf {Hence, the \: maximum \: value \: of \: {\dfrac {1}{sec \: è}} \: is \: 1}}}}}$
