Find two positive real numbers..X AND Y SAY that differ by 1 and have a product of 1.
\n" ); document.write( "X-Y=1..................................I
\n" ); document.write( "XY=1
\n" ); document.write( "(X+Y)^2=(X-Y)^2+4XY=1^2+4*1=5
\n" ); document.write( "X+Y=SQRT(5).................................II
\n" ); document.write( "EQN.I+EQN.II GIVES
\n" ); document.write( "2X=1+SQRT(5)
\n" ); document.write( "X=(1+SQRT(5))/2=(2.236+1)/2=1.618
\n" ); document.write( "EQN.II-EQN.I..GIVES
\n" ); document.write( "2Y=SQRT(5)-1
\n" ); document.write( "Y=(SQRT(5)-1)/2=(2.236-1)/2=0.618
\n" ); document.write( "
\n" );
