Verify the identity:
\n" ); document.write( " $\"%281+-+cos+x%29+%2F+%281+%2B+cos++x%29+=+%28cot+x+-+csc+x%29%5E2\"$
\n" ); document.write( "Start with right side:
\n" ); document.write( "

\n" ); document.write( "(1-cosx)^2/(1+cosx)(1-cosx)=(1-cosx)/(1+cosx)
\n" ); document.write( "verified: right side=left side
\n" ); document.write( "note:(cosx-1)^2=(1-cosx)^2 \n" ); document.write( "

\n" );
