Engineers who choose to change careers and become mathematics teachers are a specific group as far as their mathematics learning in the context of engineering and their previous work experience are concerned. Regarding mathematics, they mainly engaged in applied mathematics associated with engineering, which is a highly practical field. This…

Background: The importance of knowledge and skills in mathematics for electrical engineering students is well known. Engineers and engineering educators agree that any engineering curriculum must include plenty of mathematics studies to enrich the engineer's toolbox. Nevertheless, little attention has been given to the possible contribution of…

We write down very simple, necessary and sufficient conditions for the additive and multiplicative separability of variables: v(x[subscript 1], x[subscript 2],..., x[subscript n]) = g[subscript 1](x[subscript 1]) + g[subscript 2](x[subscript 2]) +...+ g[subscript n](x[subscript n]) or u(x[subscript 1], x[subscript 2],..., x[subscript n]) =…
