The purpose of this work is twofold: to present a computational strategy to simulate the dynamics of a rigid sphere during water sloshing and to validate the model with original e. How to make graphs of polynomial functions, regions of inequalities. If I add random data to your value of twenty or if I turn off auto scaling of the z axis, and use a range of 15 to 25, the 3D graph displays more as I would expect.
