Analyzing related rates problems: equations () | Course: AP Calculus AB > Unit 4 Analyzing related rates problems: equations Zhenghao was given this problem: The radius r (t) r(t) of a sphere is decreasing at a rate of 1 1 meter per hour. Imagine we are given the following problem: In general, we are dealing here with a circle whose size is changing over time. So that's 2 times the The rate of change of each quantity is given by its, We are given that the radius is increasing at a rate of, We are also given that at a certain instant, Finally, we are asked to find the rate of change of, After we've made sense of the relevant quantities, we should look for an equation, or a formula, that relates them.

So what's da dt Learn statistics and probabilityeverything you'd want to know about descriptive and inferential statistics. Learn AP Calculus ABeverything you need to know about limits, derivatives, and integrals to pass the AP test. In this case, the r actually does stand for radius; the function r(t) will return the value of the radius when t (time) is equal to a certain value.
