What are critical points? Why do we use them?

Critical points in a verbal definition is when f'(x)=0, however in a common sense definition it is simply the maxes or mins of f(x) because that is where the slope at that point equals 0.

Also one of it's uses is to help a person sketch a roughly accurate graph of a function.
