Find the Standard Form of the equation of the ellipse with the given characteristics and center at the origin.
\n" ); document.write( "Characteristics: Foci: (plus & minus 5, 0) , Major axis of length 12
\n" ); document.write( "***
\n" ); document.write( "Given ellipse has a horizontal major axis.
\n" ); document.write( "Its standard form of equation: \"%28x-h%29%5E2%2Fa%5E2%2B%28y-k%29%5E2%2Fb%5E2=1\", a>b, (h,k)=(x,y) coordinates of center.
\n" ); document.write( "For given ellipse:
\n" ); document.write( "Given center: (0,0)
\n" ); document.write( "Given length of horizontal major axis=12=2a
\n" ); document.write( "a=6
\n" ); document.write( "a^2=36
\n" ); document.write( "c=5 (distance from center to foci)
\n" ); document.write( "c^2=25
\n" ); document.write( "c^2=a^2-b^2
\n" ); document.write( "b^2=a^2-c^2=36-25=11
\n" ); document.write( "Equation of given ellipse:
