Polar Coordinates in AP Calculus BC: Graphs, Area & Arc Length

Introduction By describing points using a radius and an angle rather than horizontal and vertical distances, polar coordinates expand on the Cartesian coordinate system. A point in polar form is written as: where: = distance from the origin = angle measured from the positive -axis Polar coordinates are utilized in AP Calculus BC for arc […]
Parametric Curves in the Plane (AP Calculus BC) – Derivatives, Arc Length & Cycloids Explained

Introduction In standard algebra, curves are typically written as . However, many important curves in mathematics and physics cannot be expressed this way. For example, the circle: fails the vertical line test and therefore cannot be written as a single function . Why Parametric Curves Matter This restriction is overcome by parametric equations, which describe […]
