The given question is: \r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "Sin (-pi/6) \r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "We know that sin (- theta) is noth8ing but - sin (theta) \r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "That is\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "sin(-x) = - sin (x) [ here i have written x instead of theta]\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "Therefore,\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "Sin(-pi/6) = - sin(pi/6) \r
\n" ); document.write( "
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( " = - sin (30)\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "This value lies in the 3rd quadrant\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "and thus the value of this is -1/2 \r
\n" ); document.write( "
\n" ); document.write( "
\n" ); document.write( "
\n" ); document.write( "
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( " \n" ); document.write( "

\n" );
