Volumes of Solids with Known Cross Sections 3 Examples. Applications of derivatives Analysis of curves, including the notions of monotonicity and concavity. Polar coordinates are usually used when the region of interest has circular symmetry. To provide a common foundation, specific applications should include using the integral of a rate of change to give accumulated change, finding the area of a region (including a region bounded by polar curves), the volume of a solid with known cross sections, the average value of a function, the distance traveled by a particle along a line, and Get Definitions of Key Math Concepts from Chegg In math there are many key concepts and terms that are crucial for students to know and understand. But what about r f(T)? At first you might think dr dT is the slope of the tangent line to the curve but consider r = constant e. For polar curves, we do not really find the area under the curve, but rather the area of where the angle covers in the curve. Ph. The slope of the curve is still dy dx, and the concavity still depends on d2y dx2, so all that is needed is a way of differentiating with respect to x when everything 532 Chapter 10 Parametric, Vector, and Polar Functions Slope and Concavity We can analyze the slope and concavity of parametric curves just as we can with explicitly-defined curves.
