Appendix 3—figure 1. Bending vector traces and torsion of equilibrium configurations of the euglenid flagellum under four different target bending strains, and for different values of the parameter $\nu =D^p/(B^a{L}^{-2})$.

The target bending strains are given by $(u_1^{*},u_2^{*})$, with $u_2^{*}(x)=a_0+a_1\sin (2\pi x)$ and $u_1^{*}=ϵ{\tilde{u}}_1^{*}$, where (a) ${\tilde{u}}_1^{*}(x)=\sin (2\pi x)$, (b) ${\tilde{u}}_1^{*}(x)=\sin (4\pi x)$, (c) ${\tilde{u}}_1^{*}(x)=\cos (2\pi x)$, and (d) ${\tilde{u}}_1^{*}(x)=\cos (4\pi x)$.
