On the podium, Lin Xian picked up the chalk, quickly wrote a line of formulas on the blackboard, and then talked freely.

The key is that he gave lectures without writing throughout the whole process, not even a textbook, and he relied on a piece of chalk.

Lagrangian median value theorem, by name, its prover is Lagrangian, in

The name of Lagrangian was written on the blackboard and smiled and said, "In the mathematics world, theorems and conjectures are usually mentioned by

Name the name of the creator and the prover. If you see the name of a strange mathematician in the future,

It's very simple to know whether he meets awesome or not. You just need to recall whether there are any numbers named after him.

Just learn conjectures or theorems

Although not all Niu Qiang's mathematicians have proved or proposed theorems and theorems. But in their name

The mathematician who is named conjecture and theorem must be very awesome! Hearing this, the students in the classroom can do it one after another

Heart ~ Smile

They thought the substitute teacher was pretty good, he spoke very interestingly, and was not boring at all.

Before the theorem, let’s get to know this mathematician. Lagranges is a French mathematician teacher

From the first person in mathematics at that time, Euler, in the current Internet, is that the Holy Son or the Dao-Son

candidate

Hearing this, the students couldn't help but smile again.

Lin Xian held the chalk, rolled up the cuffs of the windbreaker slightly, and talked with a confident smile on his face.

"These other equation theory, solution function theory and number theory have made important contributions, Lagrangian

The median theorem is one of many achievements. Okay, after introducing the prover of the theorem, let's take a look
Chapter completed!
