\n" ); document.write( " Standard Form of an Equation of an Ellipse is \"%28x-h%29%5E2%2Fa%5E2+%2B+%28y-k%29%5E2%2Fb%5E2+=+1+\"
\n" ); document.write( "where Pt(h,k) is the center and a and b are the respective vertices distances from center.
\n" ); document.write( "\"%28x-1%29%5E2%2F13+%2B+%28y%2B6%29%5E2%2F49+=+1\"
\n" ); document.write( " C(1,-6) Yes!
\n" ); document.write( " F = \"sqrt%2849-13%29+=+sqrt%2836%29+=+6\"
\n" ); document.write( "foci are along the major axis: need to determine that major axis
\n" ); document.write( "foci are (1,0) and (1,-12)
