Why Lesson Planet?
In this chain rule and directional derivatives learning exercise, learners solve 4 different word problems related to determining points. First, they find the rate at which a trees volume grows per year when its radius is a particular number and its height is a certain number. Then, students find the directional derivative of a function at a point in the direction of the vector. In addition, they find the directions of the steepest slope and the magnitude of the slope in that direction.
