Use the word in a sentence of your own.

A function f and a point P are given. Let $\theta$ correspond to the direction of the directional derivative. Find the angles $\theta$ (with respect to the positive $x$-axis) associated with the directions of maximum increase, maximum decrease, and zero change.

$$f(x, y)=\sqrt{12-x^2-y^2} ; P(-1,-1 / \sqrt{3})$$

Which do you consider more risky-climbing Mount Everest or the sport you discussed before you read the selection? Explain your response.

What happens when you add more (or fewer) possible responses to the responses list? Will the selection of a random-response still work properly? Why or why not?
