ln(x+1) - ln(x-1)=2
\n" ); document.write( "ln((x+1)/(x-1)) = 2 = ln(e^2)
\n" ); document.write( "(x+1)/(x-1) = e^2
\n" ); document.write( "x+1 = e^2*x - e^2
\n" ); document.write( "x - x*e^2 = -1 - e^2
\n" ); document.write( "x*(e^2 - 1) = e^2 + 1
\n" ); document.write( " $\"x+=+%28e%5E2+%2B+1%29%2F%28e%5E2+-+1%29\"$ \r
