HIGHLIGHTS
- who: Chebyshev et al. from the Journal of Siberian Federal UniversityMathematics and Physics, (1), Russia have published the research work: Pseudospectral Methods for Nonlinear Pendulum Equations, in the Journal: (JOURNAL)
- how: The calculation results are shown in Tab.
SUMMARY
To resist the friction, the authors need to add some external force, to simplified the authors choose the external periodic force and so the equation of motion becomes the equation: d2 d θ(t)=-v 2 sin θ(t) - α θ(t) + β cos(wt), 2 dt dt Pseudospectral Methods for Nonlinear Pendulum Equations all the above . . .
