(a) Plots of $\rho$-cut representations of fuzzy exact solution $\left[{\underset{\_}{\omega }}_{\rho }\left(t\right),{\overline{\omega }}_{\rho }\left(t\right)\right]$ and fuzzy approximate solution $\left[{\underset{\_}{\omega }}_{\rho }^8\left(t\right),{\overline{\omega }}_{\rho }^8\left(t\right)\right]$, case I. (b) Plots of $\rho$-cut representations of fuzzy exact solution $\left[{\underset{\_}{\omega }}_{\rho }\left(t\right),{\overline{\omega }}_{\rho }\left(t\right)\right]$ and fuzzy approximate solution $\left[{\underset{\_}{\omega }}_{\rho }^8\left(t\right),{\overline{\omega }}_{\rho }^8\left(t\right)\right]$, case II, for Application 1 at $\beta =1,$ $t\in \left[0,1\right]$.
