WebConformable Dynamic Equations on Time Scales is devoted to the qualitative theory of conformable dynamic equations on time scales. This book summarizes the most recent contributions in this area, and vastly expands on them to conceive of a comprehensive theory developed exclusively for this book. Websolution of the coupled nonlinear partial differential equations was found by the Mathematica software system employing a package that applies tanh-sech methods [6]. To obtain curves from their curvatures we expand the Frenet equations numerically up to their position [2,6]. Then curves and their position
