The Chain Rule: Videos & Practice Problems

In a study of a city's traffic flow, the volume of cars on a major highway is modeled by the equation $V=\frac{730}{\pi }\sin \left(\frac{\pi }{365}(d-80)\right)+150$ where $V$ is the volume of cars and $d$ is the day of the year. About how many cars per day is the traffic volume increasing when it is increasing at its fastest?
