To find the exact solutions, we used the Laplace transform depending on the fractional derivative used. As for the approximate solutions, we used two numerical methods: the Euler method and the Runge-Kutta-4 method.enDeformable fractional derivativeLaplace transformEuler methodRunge-Kutta method -4Thesis
