Learning outcomes |
On completion of this unit, students should:
1. Parametrize regular plane curves and space curves and determine their curvature and torsion;
2. Classify curves through their curvature and torsion;
3. Recognize and parameterize regular surfaces in space and determine their curvature using local coordinates;
4. Determine the equations of the geodesics of a regular surface;
5. Classify special subclasses of surfaces.

Teaching Methodologies and Assessment Criteria |
- Theoretical-practical classes and homework;
The assessment will be based on the following elements:
1. Three tests, T1, T2 and T3, all quoted for 20 points.
2. Two mandatory assignments/exercises at home, E1 and E2, both priced at 10 points.
The final classification F, rounded to the nearest unit, is given by the formula F=0.3*T1+0.35*T2+0.3*T3+0.05*(E1+E2)
The student will pass Continuous Assessment in the curricular unit if the classification in each assessment element is equal to or greater than 5 values ??and the final classification F is equal to or greater than 9.5 values. The approved student will have a classification equal to F.
All students will be admitted to the exam.
