Some Estimates for the Solutions of the First Order Non-Algebraic Classes of Equations

Journal of Contemporary Mathematical Analysis (Armenian Academy of Sciences), 2020
In the paper the authors consider the equation \[ \varphi_{0}(z,w)(w')^m +\varphi_1 (z,w)(w')^{m-1}+\cdots +\varphi_m (z,w)=0,\tag{\(\ast\)} \] where $\varphi_i (z,w):=\sum_{m(i)=1}^{n(i)} \eta_{i,\mu(i)}(z)\chi_{i,\mu(i)}(w)$ for $i=0,1,2,\cdots,m$ and $\mu(i)=1,2,\cdots,n(i)$ with the following restrictions: all coefficient $\chi_{i,\mu(i)}(w)$ are ...

Cognitive models underlying algebraic and non-algebraic solutions to unequal partition problems

Mathematics Education Research Journal, 1998
The structure of certain word-problems can be perceived in different ways, depending on the grammatical form of presentation of the problem and the student’s expectation of how it will be solved. The results of our study involving 268 school students aged 14–16 show that, for a certain class of problems, different problem presentations promote the ...
