Algebra.Com's Answer #356073 by scott8148(6628) You can put this solution on YOUR website! 2pi is a full circle ___ 2 = 6/3 ___ so 5pi/3 is 5/6 of a circle or 300º ___ quadrant IV ___ this is a 60º reference angle\r \n" ); document.write( " \n" ); document.write( "\n" ); document.write( "x = cos(-60º) ___ y = sin(-60º) \n" ); document.write( " |
