tan theta= 2/9 and theta is in the third quadrant, find sin theta
\n" ); document.write( "-----
\n" ); document.write( "tan(t) = y/x
\n" ); document.write( "00000
\n" ); document.write( "In QIII y = -2 ; x = -9
\n" ); document.write( "-------
\n" ); document.write( "r = sqrt[4+81] = sqrt(85)
\n" ); document.write( "-------
\n" ); document.write( "sin(t) = y/r = -2/sqrt(85)
