May you give me some information about the branches of science or criterion deal with such nature ? So by some kind of “natural selection”, the are much less frequently met because theoricians and practitioners tend to avoid them.

Kepler’s third law of planetary motion involves squares and cubes of physical quantities. The outlines of the characters you are reading right now might be strings of cubic Bézier curves. But, if you don’t have the Georgia font installed, Times Roman will be displayed instead, and that uses cubic curves. The seemingly circular dot above the “i” is actually four cubic curves.

Graphics packages like OpenGL and Direct3D also use cubic curves heavily. So the curves you see in games and other 3D programs are often cubics. Whenever you do any calculations with cubic Bezier curves, you are using cubic equations. For example, if you calculate points on the curves so that you can draw them on a computer screen or a printer. If you want to intersect one of these curves with a straight line, you will have to solve a cubic equation. In short, cubic Bézier curves are everywhere.

You can start reading about all of this here. 1, I believe these are also called splines? If the polynomisl pieces are cubics, then you have a cubic spline. But cubic splines are another good example of the usage of cubic functions. Ah thanks, I wasn’t sure of the terminology but I know cubic splines are used a lot in rendering curves because once you match up endpoints, derivative, and second derivative, you have a cubic that is a very nice piecewise approximation. Eigenvalues and Eigenvectors are an essential tool in the theory of matrix computation.

I blindly copied this from a site and didn’t check. Eigen-stuff is not only important in matrix theory. And I wouldn’t be surprised that the best-fit plane is perpendicular to one of the axis of inertia of the point cloud. Coefficient of drag for the lift produced by the wing. Drag produced lifting more or less weight. For similar reasons the maximum power that can be generated by a wind turbine is proportional to the cube of the wind speed. Adam Bailey – Very true Adam.
