Funny New Year greetings for math teachers should preferably bring in some mathematical knowledge. Thank you

1. We are like scalars, with only size and no direction. You let us find the direction, let us become vectors, and let us find our dreams. I wish you health and peace in the new year. May all go well with you!

2. The trajectory of my respect always has you as the center of the circle, and it is always an increasing function. This is an absolute value. Although I want to study further, I will leave a parabola to represent my blessing to you. I wish you unlimited happiness in the new year!

3. I wish you happiness every day 365 days a year, peace of mind every moment 8760 times, comfort every moment 525600 times, and peace of mind every second 31536000 times!

4. Suppose your harvest in the new year is f(x). The calculation of f(x) is as follows:

f(x) x∈Happiness, Harvest of success; (n is a positive integer greater than 1), x∈failure, sadness and pain, 0

5, New Year’s Day is here, I wish you a flick of the finger, your worries will disappear, and you will be happy. 100%; I wish you have a "load" on your shoulders, and luck and wealth can be carried on your shoulders; I wish you can open your mouth and take a pill of elixir, feel refreshed and become an immortal. Wish you a happy New Year
