Question 1170279


{{{y=x/tan(x )}}} ...........since {{{1/tan(x ) =cot(x)}}}

{{{y(x)= x*cot(x)}}} 
{{{y(-x) = -x*cot(-x) = xcot(x) = y(x)}}}

so, {{{y=x/tan(x) }}}is an {{{even}}} function


 
{{{y=sec(x)/x}}}

{{{y(-x) = -sec(-x)/x = -sec(x)/x = -y(x)}}}

=> {{{y=sec(x)/x}}} is an {{{odd}}} function
