\n" ); document.write( "Two ground stations are located by its coordinates as A(0,0) and B(0,5),the unit being 1km. An airplane pilot conducting a reconnaisance survey knows from the radar that at a certain instant he is 3 km. nearer B than A. What is the equation of the curve that defines this data? I hope you will answer this question. Thanks.

You can put this solution on YOUR website!
So assume the plane is at (\"x\",\"y\").
\n" ); document.write( "The distance from A to the plane is \"D%5BA%5D=sqrt%28%28x-0%29%5E2%2B%28y-0%29%5E2%29=sqrt%28x%5E2%2By%5E2%29\".
\n" ); document.write( "The distance from B to the plane is \"D%5BB%5D=sqrt%28%28x-0%29%5E2%2B%28y-5%29%5E2%29=sqrt%28x%5E2%2B%28y-5%29%5E2%29\".
\n" ); document.write( "You also know that,

\n" ); document.write( "\"sqrt%28x%5E2%2B%28y-5%29%5E2%29=sqrt%28x%5E2%2By%5E2%29%2B3\"
