Right-Handed Rectangular Coordinate System, Spatial Affine Coordinate System!
Tetrahedron Median, Inscribed Sphere of Tetrahedron!
Affine Equivalence Class, the Intersection of a Hyperbolic Cylinder and a Plane Is Nonempty!
One brand-new type of problem after another unfolded before him. Strange illusions appeared before Song He's eyes as he stepped into a geometric field completely different from the past!
If his previous mathematics studies had merely been a superficial taste of ordinary knowledge,
then now, he had finally touched the edge of the mathematical abyss!
At the same time, system notifications kept appearing before his eyes.
Mathematics Progress detected, rising from Silver Level 13 to Silver Level 14! Mathematics Progress detected, rising from Silver Level 14 to Silver Level 15!
Song He's hormones surged wildly. These problems were intensely stimulating, and before he knew it, he had entered a state of bloodthirsty focus!
If this period's Mathematics Workbook was a hearty main course, then the previous period's Mathematics Workbook had been little more than peanuts. The difficulty had risen by more than one level. In hindsight, perhaps the first Mathematics Workbook had merely been a beginner's tutorial?
He was excited, but at the same time, a chill ran through his heart. Could this be the true face of the Math Competition?
Page six took eight minutes.
Page seven took seven minutes.
Page eight took five minutes!
Song He grew increasingly proficient, gradually entering the zone.
His writing grew faster and faster, and he turned pages more and more frequently!
He began to forget the time, forget the wager, and even forget the two opponents across from him who had issued the challenge. He drifted blissfully through the ocean of mathematics, unable to tear himself away from every vector and every tangent.
But the two challengers across from him
