Question 318008
<pre><b>
{{{sin(A)/sec(A)}}}{{{"+"}}}{{{cos(A)/csc(A)}}}

{{{sin(A)/(1/cos(A))}}}{{{"+"}}}{{{cos(A)/(1/sin(A))}}}

{{{sin(A)}}}{{{"÷"}}}{{{1/(cos(A))}}}{{{"+"}}}{{{cos(A)}}}{{{"÷"}}}{{{1/(sin(A))}}}

{{{sin(A)}}}{{{"×"}}}{{{(cos(A))/1}}}{{{"+"}}}{{{cos(A)}}}{{{"×"}}}{{{(sin(A))/1}}}

{{{sin(A)}}}{{{cos(A)}}}{{{"+"}}}{{{cos(A)}}}{{{sin(A)}}}

{{{sin(A)}}}{{{cos(A)}}}{{{"+"}}}{{{sin(A)}}}{{{cos(A)}}}

{{{2*sin(A)}}}{{{cos(A)}}}

There is an identity {{{sin(2theta)}}}{{{"="}}}{{{2sin(theta)cos(theta)}}}
So the above in simplest form is

{{{sin(2A)}}}
