You can put this solution on YOUR website!
You can use any unit circle picture online.\r
\n" ); document.write( "\n" ); document.write( "On the unit circle, a point is given to be (x,y) = (cosine,sine). \r
\n" ); document.write( "\n" ); document.write( "Where on the unit circle is y or sine = -1/2?\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "At y = 11pi/6, and 7pi/6, the value is given to be -1/2. \r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "One the unit circle, y or sine equals -1/2 at the two above radian values given. \r
