Meike Akveld; George Kinnear – International Journal of Mathematical Education in Science and Technology, 2024
Many universities use diagnostic tests to assess incoming students' preparedness for mathematics courses. Diagnostic test results can help students to identify topics where they need more practice and give lecturers a summary of strengths and weaknesses in their class. We demonstrate a process that can be used to make improvements to a mathematics…

Baksalary, Oskar Maria; Trenkler, Gotz – International Journal of Mathematical Education in Science and Technology, 2010
By considering a general representation of proper rotation matrices, the eigenvalues and eigenspaces of those matrices are identified.

Gauthier, N. – International Journal of Mathematical Education in Science and Technology, 2008
A general method is presented for evaluating the sums of "m"th powers of the integers that can, and that cannot, be represented in the two-element Frobenius problem. Generating functions are introduced and used for that purpose. Explicit formulas for the desired sums are obtained and specific examples are discussed.

Mamon, Rogemar S. – International Journal of Mathematical Education in Science and Technology, 2004
Within the general framework of a multifactor term structure model, the fundamental partial differential equation (PDE) satisfied by a default-free zero-coupon bond price is derived via a martingale-oriented approach. Using this PDE, a result characterizing a model belonging to an exponential affine class is established using only a system of…
