Write an equation in standard form of an ellipse that is 10 units high and 8 units wide. The center of the ellipse is (0,0)
\n" ); document.write( "..
\n" ); document.write( "Standard form of ellipse with vertical major axis and center at the origin:
\n" ); document.write( "x^2/b^2+y^2/a^2=1, a>b
\n" ); document.write( "..
\n" ); document.write( "2a=length of major axis=10
\n" ); document.write( "a=5
\n" ); document.write( "a^2=25
\n" ); document.write( "..
\n" ); document.write( "2b=length of minor axis=8
\n" ); document.write( "b=4
\n" ); document.write( "b^2=16
\n" ); document.write( "..
\n" ); document.write( "Equation: x^2/16+y^2/25=1
\n" ); document.write( "See graph below as a visual check on the answer
