If that radius shifted as an independent variable, the rotation changed in response, describing a nonlinear function.

Derivatives cannot be calculated in nonlinear functions because they do not have a well-defined slope.

It does not matter if nonlinear known functions appear in the equations.

Energy lost due to friction may be a nonlinear function of the velocity and normal forces.

In addition, the contact stresses are usually a nonlinear function of the deformation.

A nonlinear function can be defined by linear features.

This distribution can be propagated exactly by applying the nonlinear function to each point.

Applying the nonlinear function to each of the sigma points gives:

The nonlinear transcribing function can be viewed as a Taylor series.

The function F is some nonlinear function, such as a polynomial.
