Question 1135406

{{{cos^2(x)=(csc(x)*cos(x))/(tan(x) +cot( x)) }}}


{{{cos^2(x)=((1/sin(x))*cos(x))/(sin(x)/cos(x) +cos(x)/sin( x)) }}}


{{{cos^2(x)=((cos(x)/cross(sin(x))))/((sin^2(x) +cos^2(x))/(cross(sin( x))cos(x)))}}}


{{{cos^2(x)=(cos(x))/(1/cos(x))}}}


{{{cos^2(x)=cos(x)*cos(x)}}}


{{{cos^2(x)=cos^2(x)}}}
