In this section we will introduce two problems that we will see time and again in this course : Rate of Change of a function and Tangent Lines to functions. Both of these problems will be used to introduce the concept of limits, although we won't formally give the definition or notation until the next section.

Learn how to calculate the surface area, volume, and perimeter for shapes, including cylinders, cones, pyramids, polygons, circles, and more.
