verify the identity
\n" ); document.write( "secx-cosx equals sinxtanx
\n" ); document.write( "start with left side
\n" ); document.write( "secx-cosx
\n" ); document.write( "=1/cosx-cosx
\n" ); document.write( "=(1-cos^2x)/cosx
\n" ); document.write( "=sin^2x/cosx
\n" ); document.write( "=sinx*(sinx/cosx)
\n" ); document.write( "=sinxtanx
\n" ); document.write( "verified:
\n" ); document.write( "left side=right side \n" ); document.write( "

\n" );
