We need to explain what are critical points and how are they found.
The concept of "critical point" is used in a lot of different ways, particularly, the most common way in which it is used is to describe the points where the slope of the tangent line is zero in continuous functions.
So if we have a function f(x), we define the critical points as these that make:
f'(x) = 0.
These critical points appear in a lot of things, for example, the maximum height of something that you throw upwards is given by the critical point in its position.
On other fields, we also define critical points as points of change, for example, we can define the critical temperature as the temperature such that a material stops being a superconductor. (the critical temperature is a critical point)
To get these critical points you usually need to do some experimentation and then find a model for them.
