Use identities and definitions to show that cos theta = sin theta cot theta
\n" ); document.write( "--------------
\n" ); document.write( "cos theta = sin theta cot theta\r
\n" ); document.write( "\n" ); document.write( "cot = cos/sin
\n" ); document.write( "cos = sin*(cos/sin)
\n" ); document.write( "cos = cos
\n" ); document.write( "QED
\n" ); document.write( "
\n" );
