y=1-#8721;(from n=0 to infinity){8/[(2n+1)^2*#960;^2]} x exp{-[(2n+1)^2*#960;^2*D*t]/ 4*L^2} where: y-provided in second column above, D-unknown value-trying to find it, L-constant, t-time. However, when I try to use the code it doesn't work and I also tried to follow the previous post (http://www.originlab.com/forum/topic.asp?TOPIC_ID=4761)without success so I would really appreciate your help.
