We use Mathematica when we are plotting the graphs of examples.
📌 3 Key Takeaways
🎯
Objective & Hypothesis:In the present study, firstly we recall the parametric expressions of planar curves with zero phi-curvature in Euclidean 3-space with density e^ax_1 and with the aid of the Frenet frame of these planar curves, we obtain the Smarandache curves of them.
📊
Key Findings & Data:After that, we study on ruled surfaces which is constructed by curves with zero -curvature in Euclidean 3-space with density e^ax_1 and their Smarandache curves by giving the striction curves, distribution parameters, mean curvature and Gaussian curvature of these ruled surfaces.
💡
Conclusion & Impact:We use Mathematica when we are plotting the graphs of examples.
