For example for an ellipsoid with principal axes 3, 2 and 1 along the x, y and z coordinate axes respectively, with center at the origin and truncated at x equals 1.

What math will reveal its center of mass and its moment of inertia for an axis of revolution through the center of mass and parallel to the y axis?

This worksheet has an error when executing EulerLagrange.

How can this error be avoided?

Initial text in the uploaded worksheet describes an attempt to partially tile the Poincare disk and asks to be shown how a known complex transformation can be used to accomplish this.

The worksheet below contains the desired hyperbolic action and asks for the specific transformation that performs it.

I have corrected the above worksheet so that the Poincare disk is now centred at [0,0].

I hope this helps you answer my question

In the worksheet below is an equation for non-Euclidean lines. How can Maple plot these?
