Inverse Variation - Problem 3
If two points vary inversely, that means that the product of the x and y values of the first point is equal to the product of the x and y values of the second point. This is known as the product rule
for inverse variation: given two ordered pairs (x1, y1) and (x2, y2), x1y1 = x2y2.

Abel's Lemmas on Irreducibility
In today's blog, I present a few lemmas that Niels Abel published on irreducibility. These lemmas are used in Abel's proof on the insolvability of the quintic equation.
