Draw the hyperbolas and the eccentricity of the following:
\n" ); document.write( "4x^2 - 9y^2 - 16x + 18y = 29
\n" ); document.write( "complete the square
\n" ); document.write( "4x^2-16x-9y^2+18y=29
\n" ); document.write( "4(x^2-4x+4)-9(y^2-2y+1)=29+16-9
\n" ); document.write( "4(x-2)^2-9(y-1)^2=36
\n" ); document.write( "\"%28x-2%29%5E2%2F9-%28y-1%29%5E2%2F4=1\"
\n" ); document.write( "This is an equation of a hyperbola with horizontal transverse axis.
\n" ); document.write( "Its standard form of equation: \"%28x-h%29%5E2%2Fa%5E2-%28y-k%29%5E2%2Fb%5E2=1\", (h,k)=(x,y) coordinates of center
\n" ); document.write( "For given equation:\"%28x-2%29%5E2%2F9-%28y-1%29%5E2%2F4=1\"
\n" ); document.write( "center: (2,1)
\n" ); document.write( "a^2=9
\n" ); document.write( "a=√9=3
\n" ); document.write( "b^2=4
\n" ); document.write( "b=√4=2
\n" ); document.write( "c^2=a^2+b^2=9+4=13
\n" ); document.write( "c=√13
\n" ); document.write( "eccentricity=c/a=√13/3 (there is no graph for this)
\n" ); document.write( "see graph below
\n" ); document.write( "y=±(4(x-2)^2/9-4)^.5+1
\n" ); document.write( "\r
