verify the identity:
\n" ); document.write( "sin^2(x) + sin^2(x)*tan^2(x) = tan^2(x)
\n" ); document.write( "--------
\n" ); document.write( "sin^2(x)[1+tan^2(x)] = tan^2(x)
\n" ); document.write( "--------
\n" ); document.write( "sin^2(x)[sec^2(x)] = tan^2(x)
\n" ); document.write( "--------
\n" ); document.write( "= sin^2(x)/cos^2(x) = tan^2(x)
\n" ); document.write( "-------
\n" ); document.write( "= tan^2(x) = tan^2(x)
