This course will use methods from multi-dimensional analysis to develop the local differential geometry of curves and surfaces in Euclidean space. In this way, the course provides an introduction to an area of active research in mathematics.

Learning Outcomes:
At the end of the course, the students will be able to apply the methods of calculus with confidence to geometrical problems. They will be able to compute the curvatures of curves and surfaces and understand the geometric significance of these quantities. Through their coursework, the students will be able to demonstrate a deep understanding of an area of differential geometry.

Analytic skills T/F A; Problem solving T/F A; Written communication F A.
