Find the exact values of sin(θ/2), cos(θ/2), and tan(θ/2) for the given conditions.
\n" ); document.write( "sec θ = −5/3; 180° < θ < 270°
\n" ); document.write( "----
\n" ); document.write( "Note:: cos(t) = -3/5
\n" ); document.write( "----
\n" ); document.write( "sin(t/2) = sqrt[(1-cos(t))/2] = sqrt[8/10] = sqrt(0.4) = 0.6325
\n" ); document.write( "------------
\n" ); document.write( "cos(t/2) = sqrt[(1+cos(t))/2] = sqrt(0.2) = 0.4472
\n" ); document.write( "------------
\n" ); document.write( "tan(t/2) = sin(t/2)/cos(t/2) = 0.0001414..
\n" ); document.write( "---------------------------
