You can put this solution on YOUR website!
tan(x/2)
\n" ); document.write( "= sin(x/2)/cos(x/2)
\n" ); document.write( "=(sqrt((1-cos x)/2))/(sqrt((1+cos x)/2)
\n" ); document.write( "=sqrt((1-cos x)/(1+cos x))
\n" ); document.write( "=sqrt((1-cos x)^2/(1-cos^2 x))
\n" ); document.write( "=sqrt((1-cos x)^2/(sin^2 x))
\n" ); document.write( "=(1-cos x)/(sin x)
\n" ); document.write( "=1/sin x - cos x/sin x
\n" ); document.write( "= csc x - cot x \n" ); document.write( "

\n" );
