changes from as it passes through a critical point, the point is a relative maximum .
$$\fracdVdt = \frac43\pi (3r^2) \fracdrdt$$$$\fracdVdt = 4\pi r^2 \fracdrdt$$
Especially in Related Rates and Optimization, keeping track of units (e.g.,
The chapter opens with a review of geometric interpretation. You will learn how to find the slope of a curve at any given point, but more importantly, you will solve for: changes from as it passes through a critical
) represents the instantaneous rate of change or the slope of a curve at any given point. Chapter 4 leverages this geometric and physical meaning to solve problems in several key areas: Related Rates Curve Sketching (Maxima, Minima, and Inflection Points) Optimization Problems Newton's Method (Approximations) 1. Tangent and Normal Lines to Curves
They illustrate how to use derivatives to solve these problems.
The chapter begins by reviewing the geometric interpretation of derivatives. The authors recall that the derivative of a function f(x) represents the slope of the tangent line to the graph of f(x) at a point x=a. This is denoted as f'(a). Chapter 4 leverages this geometric and physical meaning

Feliciano and Uy use the extensively here. You will be asked to find intervals where a function is rising or falling and identify relative maximums and minimums.
The chapter introduces several "short-cut" theorems that are essential for all subsequent calculus topics:
