Sometimes they're loosely used interchangeably, but typically when you're asked to identify a critical point, you're expected to provide the coordinates of the point (both x and y), and a critical number is …

Lesson 2: Extreme value theorem, global versus local extrema, and critical points Extreme value theorem Critical points introduction Finding critical points

If we find a critical point, where the derivative is 0, or the derivative is undefined, is that going to be a maximum or minimum point? And to think about that, let's imagine this point right over here.

Once you find a critical point, how can you tell if it is a minimum, maximum or neither? Created by Sal Khan.

Calculate the approximate sample size required to obtain a desired margin of error in a confidence interval for a mean.

So, let's go to the thousandths place. And you might say, "Hey, "this top number doesn't have a thousandths digit." Well, you could just put a zero there. And so, we could first think about adding …

Learn how to calculate the mean by walking through some basic examples & trying practice problems.

Oops. Something went wrong. Please try again. Uh oh, it looks like we ran into an error. You need to refresh. If this problem persists, tell us.

So before I even ask you to pause this video, let me just give you a little reminder of what a critical value is. Remember, the whole point behind confidence intervals are we have some true population …

The first derivative test is the process of analyzing functions using their first derivatives in order to find their extremum point. This involves multiple steps, so we need to unpack this process in a way that …
