In this paper, the authors present the application of the scaffolding technique in drawing graphs of some elementary functions. First-year students of the Faculty of Architecture, Civil Engineering, and Geodesy were tested using two exams: an entrance test and an exit test. The obtained results show whether students are more successful in drawing g...

In this paper we introduce nested trigonometric and hyperbolic polynomials of rank n by employing nested trigonometric and hyperbolic functions, respectively. Our investigation delves into some interesting properties of nested polynomials, establishing some recurrence formulas and deriving some useful summation formulas. Additionally, we establish ...

The paper analyzes gender differences in the length of study and average grade between the number of enrolled and graduated students at the Faculty of Architecture, Civil Engineering and Geodesy in Banjaluka, during the period from 1996 to 2015. It was concluded that women, in civil engineering studies, are just as successful as men. However, it is...

In this paper we used a new class of special functions and special polynomials which are solutions different Sturm Liouvile differential equations of second order. These functions form a basis of a space of square integrable functions over set of a real numbers. We investigated some properties of these polynomials and established some recurrence fo...
