Re: 回复: Re: Do you like maths?
Wow sounds complex.Iruka said:Yep - even if you solve 'em using Laplace transforms you still get the characteristic polynomial popping out and you need to know how to solve it.
Actually, I am constantly being impressed by just how much you do use what you learn in senior high schools maths later on. e.g., you need to know all about partial fractions if you want to invert a Laplace transform.
I have been learning about Lyapunov functions this weekend (which is a thing that you use when analyzing a dynamical system to show whether an equilibrium point is stable or unstable) - remember all that stuff about positive definite and negative definite quadratics? Well, you need to know that terminology to understand how a Lyapunov function works.
