Let l and m be two lines in ordinary Euclidean geometry intersecting at point O. Let A, B and C be three distinct points on l and A', B' and C' three distinct points on m (none of them equal to O). Suppose that AB' is parallel to BA', and AC' is parallel to CA'. Prove, using Pappus' theorem in the Extended Euclidean Plane, that BC' and CB' are parallel.

Give a proof by contradiction to show that if two lines l and m are cut by a transversal in such a way that the alternate interior angles, x and y, have the same measure, then the lines are parallel. Write the "if, then" statement for the proof by contradiction and the proof.

In Schwarzschild geometry, the distance between two circles with different circumferences is larger than the Euclidean result, because the distance between the two circles is given by integrating dr/ (1 − rs/r) (where rs is a positive constant) along the radial path between them. Invent an embedding of the radial part of the Schwarzschild spatial geometry in one extra Euclidean dimension, that we will call the z dimension. What is the relationship between dr and dz of the one-dimensional “surface”...

A mechanical aim rotates in the vertical plan about point O. The slider P (m = 2 kg) is drawn toward O with a constant speed (?̇) of 0.5 m/s through the rough slot (friction coefficient µ = 0.1) by pulling on the free end E of the cord. At the instant when r = 0.25 m, the arm is rotating with a constant speed (?̇) of 10 rad/s in the clockwise direction. When the slider is oriented at an...
