\n" ); document.write( "\n" ); document.write( "The angle 3pi/2 is pointing directly south toward 270 degrees.
\n" ); document.write( "The associated point on the unit circle is (0,-1)
\n" ); document.write( "x = 0
\n" ); document.write( "y = -1
\n" ); document.write( "The y value is result of sin(3pi/2) because
\n" ); document.write( "x = cos(theta)
\n" ); document.write( "y = sin(theta)\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "Therefore, sin(3pi/2) = -1\r
