$\"a%5E2+=+49\"$ so a=7, $\"b%5E2+=+64\"$ , so b 8
\n" ); document.write( "Foce are at [c1,0]and [c2,0]
\n" ); document.write( "TO find foci:
\n" ); document.write( "49-64=-15 take the square root of that to get c=-3.8.
\n" ); document.write( "hence the centre at: (0,0)
\n" ); document.write( "Vertices at: (7,0) and (-7,0)
\n" ); document.write( "End points of Minor axis at: (0,8) and (0,-8)
\n" ); document.write( "Foci: (-3.8,0) and (3.8,0)
\n" ); document.write( "Paul. \n" ); document.write( "
