A general approach to three-variable inequalities
Autor: H. B. Griffiths, Adrian Oldknow
Publikováno v: The Mathematical Gazette. 82:8-18
In tackling a problem, we needed to show that a certain 3 × 3 determinant is non-zero. This determinant could be expressed in terms of the symmetric, homogeneous function N = Σx.Σx2 + 6xyz - 2Σx3 of three variables, where, for example Σx2 = x2 +

Cubic Equations, or Where Did the Examination Question Come From?

approached it with an interaction method, using a micro, and the other a "bare hands" traditional technique, and we then compared our efforts. This led us to find infinite families of related examination questions. As a by-product we found infinite f

The topography of 2 x 2 real matrices, III†
Autor: H. B. Griffiths
Publikováno v: International Journal of Mathematical Education in Science and Technology. 10:601-612
This paper has two aspects, one mathematical, the other in mathematics education. Mathematically, it investigates the bifurcation set K of the linear differential equation x = Ax on the plane, when the real 2x2 matrix A is regarded as a point in four
