The product of two or more homogeneous polynomials is also a homogeneous polynomial, with a degree equal to the sum of the factor’s degrees. If all of the factors are not homogeneous, then the product is also not homogeneous. If the polynomial factors aren’t homogeneous, then neither is ...
To obtain an understanding of the varying argumentation on whether to use dT and the argumentation used in the reasoning, we looked for participants with different degrees of experience. Pre-service mathematics teachers at the beginning of their university studies, who had limited exposure to didactic...
