There a lots of ways that you will hear about. Here is one: Solve[Tan[45*Degree]* x + (Sin[108.25718805973634]*(-Sqrt[(-0.425185)^2 + 0.843815^2]))/ Sin[135*Degree] == 0, x] Part[%, 1, 1, 2] 1.32538 -- David Park djmpark at comcast.net http://home.comcast.net/~djmpark/ "Lea Rebanks" <lrebanks at netvigator.com> wrote in message news:fphcce$8c8$1 at smc.vnet.net... > Hi All, > > After evaluating the following . > > Solve[Tan[45*Degree]*x + (Sin[108.25718805973634]* > (-Sqrt[(-0.425185)^2 + 0.843815^2]))/ > Sin[135*Degree] == 0, x] > {{x -> 1.3253773537632034}} > > I wish to extract the value only . 1.3253773537632034 > > Any advice or help gratefully received. > > Many thanks. > Best Regards - Lea Rebanks... > >
