I'm studying some differential equations material. I would like to implement something analogous to Picard's iteration method to obtain flow-line approximations for arbitrary vector fields. So I need ...

In support of efforts to foreground functions as central objects of study in algebra, this study provides evidence of how secondary students use trigonometric functions in contextual tasks. The author ...

Abstract: This paper generalizes the geometric representation of membership functions comprising a finite number of characteristic points. An extended class of membership functions, satisfying certain ...
