Focus at (0,1); 4/3 is One-Half the Length of Minor Axis.
\n" ); document.write( "Write equation of the ellipse that has center at the Origin.
\n" ); document.write( "**
\n" ); document.write( "This is an ellipse with vertical major axis. Standard form of equation:
\n" ); document.write( "(x-h)^2/b^2-(y-k)^2/a^2=1, a>b, (h,k) being (x,y) coordinates of the center.
\n" ); document.write( "center:(0,0)
\n" ); document.write( "One-Half the Length of Minor Axis=4/3=b
\n" ); document.write( "b^2=16/9
\n" ); document.write( "c=distance from center to focus=1
\n" ); document.write( "c^2=1^1=1
\n" ); document.write( "c^2=a^2-b^2
\n" ); document.write( "a^2=c^2+b^2=1+16/9=9/9+16/9=25/9
\n" ); document.write( "Equation of given ellipse:
\n" ); document.write( "9x^2/16+9y^2/25=1
\n" ); document.write( "
\n" );
