Week 01: Limits and Continuity in Higher Dimensions

We could begin by saying that limits are important in calculus, but that would be amajor understatement.Without limits, calculus would not exist. Every single notion ofcalculus is a limit in one sense or another. For example,What is the slope of a curve? It is the limit of slopes of secant lines. What is the length of a curve? It is the limit of the lengths of polygonal paths inscribedin the curve. What is the area of a region bounded by a curve? It is the limit of the sum of areas ofapproximating rectangles.
