how to put : 5x^2+9y^2+1 into standard form for ellipse\r
\n" ); document.write( "\n" ); document.write( "..
\n" ); document.write( "standard form for ellipse, x^2/a^2+y^2/b^2=1
\n" ); document.write( "given equation :5x^2+9y^2+1
\n" ); document.write( "=x^2/(1/5)+y^2/(1/9)=1\r
\n" ); document.write( "\n" ); document.write( "a^2=1/5
\n" ); document.write( "a=sqrt(1/5)
\n" ); document.write( "b^2=(1/9)
\n" ); document.write( "b=(1/3)\r
\n" ); document.write( "\n" ); document.write( "Since the denominator,(1/5), of the x^2 term is greater than the denominator,(1/9), of the y^2 term, this is an ellipse with a horizontal major axis.Its center is at (0,0).
\n" ); document.write( "
\n" );
