“…l ¼ 1 À y 5 cos y 4 þ y 6 sin y 4 ð Þ =k 2 g ; B 1 , and B 2 , are matrixes of order 5 · 8 and 3 · 8, respectively, with their elements all vanishing except for B 1 (1, 1) = B 1 (2, 3) = B 1 (3, 4) = B 1 (4, 5) = B 1 (5, 7) = B 2 (1, 2) = B 2 (2, 3) = B 2 (3, 4) = 1, Here, the load parameter p is taken as an unknown function of n in order to form a standard procedure for dealing with this kind of non-linear boundary-value problems (Li and Cheng, 2000;Li et al, 2002;Li and Zhou, 2001). It is obvious that Eq.…”
