This is just to record my progress, albeit being slow, in what I aim in the following article: It really took time, but I had to ensure I cover various themes of Arithmetic of Elliptic Curves and some ...

Revise the different types of angles and rules for calculating angles. This guide includes interactive activities and a quiz. NEW: Angles in parallel lines Revise alternate, correspondent or ...

Various aspects of the differential geometry of the tangent bundle of a differentiable manifold are examined, and the results applied to time-independent Lagrangian dynamics. It is shown that a ...
