Question 1161465
 {{{(tan(x)+cot(x))/sec^2(x)}}}

use identities: 


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

{{{tan(x)=sin(x)/cos(x)}}}

{{{cot(x)=cos(x)/sin(x)}}}



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


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


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


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


{{{cos(x)/sin(x)}}}


{{{cot(x)}}}
