First derivative test find local extrema

The video tutorial explains how to find local extrema using derivatives. It covers the process of finding the derivative, identifying critical values, and using the unit circle to find solutions. The tutorial also discusses analyzing critical values to determine maxima and minima, and testing intervals to understand function behavior. The importance of understanding these concepts for calculus assessments is emphasized.

What are the implications of a function being continuous on its critical values?

How do you determine if a critical value is a maximum or minimum?

Explain the relationship between the sign of the derivative and the behavior of the function.

What is the importance of checking intervals when determining local extrema?
