It is therefore called the triple point of the substance, and it represents the only point in the phase diagram in which all three states are in equilibrium. Point C is the critical point of the substance, which is the highest temperature and pressure at which a gas and a liquid can coexist at equilibrium. The figure below shows what happens when we draw a horizontal line across a phase diagram at a pressure of exactly 1 atm.
Let me just start with an example: Find the critical points of y=x-2sinx on [o, pi2]. So I know you first find the derivative and then set it equal to zero, yielding f'(x)=1-2cosx=0. I know that this is true when x=pi/3 and 5pi/3 but I do not understand how to get these values....I don't know how to utilize the unit circle in order to find the critical points of trig functions.
