Question 1114589
{{{(1/(1-sin(x)))((1+sin(x))/(1+sin(x)))}}}


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


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


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


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


{{{sec^2(x)+tan(x)*sec(x)}}}


and then commutative property for multiplication, for the term on the right in the expression
