The point P is on the unit circle. Find P(x, y) from the given information.
\n" ); document.write( "The y-coordinate of P is -1/9, and the x-coordinate is positive.
\n" ); document.write( "---------------
\n" ); document.write( "The unit circle is $\"x%5E2+%2B+y%5E2+=+1\"$
\n" ); document.write( "Sub -1/9 for y
\n" ); document.write( " $\"x%5E2+%2B+1%2F81+=+1\"$
\n" ); document.write( " $\"x%5E2+=+80%2F81\"$
\n" ); document.write( " $\"x+=+4%2Asqrt%285%29%2F9\"$
\n" ); document.write( " \n" ); document.write( "
