これでいうと凍結期間中に研究してたやつがあります これはパスカルの三角錐の5段目ですが、これは赤関数の5乗と関係しています これを踏まえると双曲線関数のそれは、パスカルの三角錐ではなく”パスカルの二角錐”とでも呼びたい気持ちになります

There is also a tweet from Melville with the following content:
During the freeze period, I was researching something. This is the 5th row of Pascal’s triangle, which is related to the 5th power of the red function. Based on this, I feel like calling the hyperbolic function the “Pascal’s biconical function” instead.
