We have to get d on one side and everything else on the other.
\n" ); document.write( "(5 / 1.045) + [ 105 / (1 + d2)^2 ]=100
\n" ); document.write( "105/(1+d^2)^2=100-(5/1.045)
\n" ); document.write( "=(104.5-5)/1.045
\n" ); document.write( "=99.5/1.045
\n" ); document.write( "(1+d^2)^2/105=1.045/99.5
\n" ); document.write( "(1+d^2)^2=105*1.045/99.5
\n" ); document.write( "=1.027963819...
\n" ); document.write( "1+d^2=sqrt(1.027963819...)
\n" ); document.write( "=1.050125621
\n" ); document.write( "d^2=1.050125621... -1
\n" ); document.write( "=0.050125621...
