Linearisation is the process of trying to linearise a nonlinear function. This is so that we can understand what is happening at equilibrium points.
First, find equilibrium points where f(Y) = 0.
Next, differentiate these points with respect to t.
If f'(Y) If f'(Y) > 0 then Y is unstable.
If f'(Y) = 0 then revisit the Taylor Series expansion.
