The point P is on the unit circle. Find P(x,y) from the given information. The x coordinate of P is 4/5 and P is in Quadrant I.
\n" ); document.write( "-------
\n" ); document.write( "Since the point is on the circumference of a unit circle,
\n" ); document.write( "x^2 + y^2 = 1
\n" ); document.write( "---------------------------
\n" ); document.write( "Your point is ((4/5),y) and y is positive
\n" ); document.write( "(4/5)^2 + y^2 = 1
\n" ); document.write( "y^2 = (25/25)-(16/25)
\n" ); document.write( "y^2 = 9/25
\n" ); document.write( "y = 3/5
\n" ); document.write( "-------------------
