New Year greetings written with mathematical knowledge.

As we all know, happiness can be accumulated and time is negligible, so my blessing to you is continuous! What Rolle's theorem can't prove is that Lagrange can't be deduced, and because the curve of memory is convex and the curve of missing is concave, there is no point of forgetting you. To sum up, happiness is convergent, waiting is unique, and my blessing to you is always monotonous and increasing. I wish you trouble, high-end unlimited mobile phone holiday blessing message is small, good luck is constant, inspiring, the ideal must be L'H?pital, Lagrange shines every day, life is not monotonous, the road is not bumpy, f' (mood) > 0, lim happy = positive infinity, I wish you a happy holiday.
