Prove:
\n" ); document.write( "use x for theta:
\n" ); document.write( "sin(90 degree-theta) /1+sin theta+cos theta/1-cos(90 degree-theta) =2sec theta
\n" ); document.write( " $\"cos%28x%29%2F%281%2Bsin%28x%29%29%2B%28cos%28x%29%2F%281-sin%28x%29%29%29\"$
\n" ); document.write( "

\n" ); document.write( " $\"2cos%28x%29%2Fcos%5E2%28x%29\"$
\n" ); document.write( " $\"2%2Fcos%28x%29=2sec%28x%29\"$
