Top Students Don't Need Superpowers

"What, what?" Guqiao Wennai raised his hand to cover his cheek, and said in a shameful voice, "A famous detective or something, I can only be regarded as a third-rate detective at best, right?"

You have the nerve to say so!You can't even learn basic trigonometric functions. Once you encounter a mathematical puzzle in the process of solving a case, you will be eliminated in an instant!Let alone a third-rate detective, your current level is not even considered as a detective assistant. Watson can still find clues for Sherlock Holmes. Apart from your blank eyes and cuteness, you only have the role of a snack destroyer!

Asakawa Naoki continued: "The famous detective Guqiao bit his pipe and walked into the victim's house."

"I don't know how to bite a pipe." Guqiao Fumino murmured in a low voice, "Smoking is harmful to your health. I hate the smell of cigarettes the most. Don't smoke in the future..."

"what?"

"No, it's nothing." Guqiao Fumino covered her pink lips with her right hand, and said with erratic eyes, "Student Asakawa continued."

"Walking into the house, the famous detective Guqiao soon made his first discovery. The dome of the victim's room was actually round."

Naoki Asakawa took the draft paper and drew a semicircle on the paper.

"Round roof?" Fumino Guqiao blinked his eyes and asked curiously, "Could it be a hobbit?"

The graphic curves of all trigonometric functions are very smooth. Compared with the bony hobbit, the chubby dwarf is more in line with the image!

"Don't talk, keep listening." Asakawa Naoki has a serious expression, "You are a detective now, shouldering the mission of finding the murderer and avenging the victim, don't jump to conclusions casually, that will let the real murderer go unpunished. "

"understood."

Fumino Furuhashi pursed her beautiful lips, opened her eyes wide and continued to listen to Naoki Asakawa's narration of the case.

"In addition to the domed roof, there is a suspended movie screen in the room..."

Naoki Asakawa drew a line perpendicular to the ground on the ellipse with a pen, "This is the movie screen."

Then draw a point in the middle of the bottom line, "You stand in the middle of the room and look towards the top of the movie screen, this line is your line of sight."

Naoki Asakawa connected the dots and lines on the paper, quickly drew a triangle, and turned to look at Fumino Furuhashi, "The so-called sine function is the ratio of the distance between this movie screen and you."

"The farther away you are, the smaller the screen is, and the closer you are, the bigger the screen will be." Asakawa Naoki turned the pencil at his fingertips, wrote down the basic formula of the sine function, turned to look at the ancient bridge, and asked, "What do you think of this When will the screen be the largest?"

"That, that..." Guqiao Wennai stretched out a bright white jade finger, brushed across the paper, and asked hesitantly, "When it hangs down from the middle of the roof?"

"Very good, that's right." Naoki Asakawa nodded slightly, "Congratulations to the famous detective Guqiao for successfully finding the first clue."

"It's all thanks to Asakawa-san, it has nothing to do with me."

Saying this, the corners of the literary girl's pink lips clearly outlined a happy arc upwards.

In a sense, girls, like pets, need to be rewarded from time to time, and Naoki Asakawa undoubtedly does the same.

Asakawa Naoki continued: "When the movie screen is the largest, what is the line of sight with you?"

"It's ninety degrees."

Guqiao Fuminai quickly said: "This kind of question is still not difficult for me to say."

"The answer is correct. Congratulations to Your Highness Guqiao for finding the second clue. This is where the maximum value of the sine function lies."

Asakawa Naoki picked up the pencil with his fingertips and drew a plane coordinate axis with the ancient bridge as the center, "After careful observation, the famous detective Guqiao found that there was an identical semicircular building and movie screen underground, because it was upside down. See, so it's a negative angle..."

Naoki Asakawa drew the standard graphic curve of the sine function on the paper, and continued to ask: "How many degrees should it be here?"

"that……"

Guqiao Wennai hesitated, and said in a low voice, "Ninety degrees?"

"What about when it's zero?"

"One hundred and eighty degrees."

"Very good, all the answers are correct." Naoki Asakawa marked the degrees corresponding to the maximum and minimum values ​​of the function curve on the image, and finally concluded, "The sine function is the size of the movie screen at home."

"In the same way, the cosine function is the distance from the movie screen to you..."

"I understood."

Fumino Furuhashi tilted his head and looked over, his pretty face was full of curiosity: "But Asakawa-san hasn't said why the victim was murdered yet?"

Chapter 350 Girls' Final Fear

Asakawa Naoki crossed his fingers and continued:

"The famous detective Miss Guqiao frowned, and found another clue..."

"I'm not frowning."

Guqiao Wennai whispered.

"The plot needs it, don't worry about it so much." Naoki Asakawa cleared his throat, and continued to read, "Looking up, it turned out that there was a skylight on the round roof, and the famous detective Furuhashi intuitively felt that this skylight was very strange. , so I stepped on the ladder to push the skylight open, and then saw..."

"See what?"

Guqiao Fuminao became a little nervous, and whispered: "The clues left by the murderer?"

Seeing Naoki Asakawa turn his head to look over, Fumino Furuhashi's pretty face blushed slightly, he hesitated and said, "There are similar plots in detective novels, after a criminal commits a crime, he leaves clues to provoke him, and after a battle of wits, a famous detective Yong, finally bring the other party to justice..."

"I'm sorry, the answer was wrong." Naoki Asakawa said expressionlessly.

"Wrong, wrong?"

Guqiao Fumina suddenly withered.

"The famous detective Guqiao took a closer look, and it turned out that outside the window was an endless high wall, and a huge movie screen was hung on the wall."
