Comparison of composite expansions for the membrane shape to the shapes obtained through numerical solution of (3.1)–(3.2), for A=0.65 and (a) W0=2.5×10−1 and (b) W0=6×10−2. In (b) near x=0, the plots for δA=6×10−3 are the higher of the two composite expansions and the lower of the two numerical solutions. (Online version in colour.)
