Chapter 293: Slapping Fu Chen's Face, Sending Him Offline! (1)

Lu Sheng's proof process, casually written on the blackboard, directly shocked everyone else in the class, including Zhou Wu.

This method was indeed much simpler and more sophisticated than the one provided in the reference answer.

Even compared with it, the whole page of proof process in the reference answer seemed superfluous.

The question Lu Sheng asked, although in a cool and indifferent tone, carried the oppressive aura of a top-tier student.

It was as if she was saying, "Do you think I, who can think of a simpler solution, would be dumb enough to spend twice the time writing so much?"

But it wasn't over yet.

The other students below the stage didn't expect the girl on the stage to continue, "But in fact, I thought of an even simpler proof method than trigonometric substitution during the exam."

Saying this, she picked up the chalk without caring about people's reactions, turned around, and started writing and drawing on the blackboard again.
