The expression cot(-200) degrees is equivalent to
\n" ); document.write( "1) -tan 20 degrees 2) tan 70 degrees 3) -cot 20 degrees 4)cot 70 degrees
\n" ); document.write( "**
\n" ); document.write( "Cot (-200º) makes a reference angle of 20º in quadrant II where cot<0
\n" ); document.write( "So Cot (-200º)=-cot 20º
\n" ); document.write( "
\n" );
