If tan £ = 2 with £ in Quadrant III, find sec £.
\n" ); document.write( "tan = y/x = 2/1
\n" ); document.write( "In QIII, y = -2 and x=-1
\n" ); document.write( "-------
\n" ); document.write( "r = sqrt[2^2+1^2] = sqrt(5)
\n" ); document.write( "----
\n" ); document.write( "sec = r/x = -sqrt(5)
\n" ); document.write( "========================
