Laplacian
Arthur Maclaurin, a man who has studied calculus was about to enter a dungeon.
In this world, most of materials are dropped from monsters settling in dungeons. To defeat monsters, we have to make all of the bases of monsters 0 or infinite. If your bases become 0 or infinite before monsters’ bases become it, you die.
Arthur had 1, x, and x^2 as basic set of bases. To protect himself, He added sin x to his bases.
Trigonometric functions are strong protections since they can’t become 0 by differential or integral calculus. Moreover, due to the fact that they are periodic functions, they can’t be diverged to infinite.
He encountered slime, the weakest monster settling in the first floor in the dungeon. The reason why it is the weakest is because the only action he can do is to differentiate enemy’s basis. Due to the fact, if an
adventurer has exponential or trigonometric function, he just can’t die.
The slime’s bases were 1 and x.
“Laplacian!” Arthur chanted. The slime’s bases became the second derivatives, and Arthur won the battle.
Unfortunately, nothing dropped from the slime.
