Find exact value of:
\n" ); document.write( "Sin(pie/12)
\n" ); document.write( "---------
\n" ); document.write( "pi/12 = (pi/3)-(pi/4)
\n" ); document.write( "---------
\n" ); document.write( "sin(pi/12) = sin[(pi/3)-(pi/4)]
\n" ); document.write( "---------
\n" ); document.write( "= sin(pi/3)*cos(pi/4)-sin(pi/4)*cos(pi/3)
\n" ); document.write( "---------
\n" ); document.write( "= (sqrt(3)/2) * (sqrt(2)/2) - (sqrt(2)/2) * (1/2)
\n" ); document.write( "---------
\n" ); document.write( "= sqrt(6)/4 - sqrt(2)/4
\n" ); document.write( "-----------
\n" ); document.write( "= [sqrt(6)-sqrt(2)]/4
\n" ); document.write( "=========================
