For the given value of t determine the reference angle t ' and the exact values of sin t and cos t.
\n" ); document.write( "t = 4π/3
\n" ); document.write( "t '= radians
\n" ); document.write( "sin t =
\n" ); document.write( "cos t =
\n" ); document.write( "***
\n" ); document.write( "reference angle t'=π/3 in quadrant III in which sin<0, cos<0
\n" ); document.write( "sin t=sin(π/3)=-√3/2
\n" ); document.write( "cos t=cos(π/3)=-1/2
\n" ); document.write( "
\n" );
