S4.120 - One, Singular Translation

Nat, Tangent's inverse and the resident medical expert, decided he might as well break the silence again. "So you were saying something about word origins?" he said gruffly to Root.

"Well, sure. For instance, do you know why Sine is called sine?" the silver haired man countered.

"Yes," Sine's twin sister cut in. "And I know why I'm called Cosine. It's short for Complement of Sine. In fact, you can check Ask Dr. Math about the rest of my family. It has many links there too!"

"Okay, then let's move to considering languages in general," Lyn suggested.  "For instance, in French we're 'les mathématiques'... does that make us male or female?"

"Plural.  I think the lack of singular means we're permanently dating," Elly opined.

Important: The same mathematical family does not imply blood relations.

Secant frowned. "Ugh. We're not getting into that whole arranged marriage subtext between functions and their inverses, are we?"

"What subtext? I like dating Para!" Root countered with a grin.

Lyn palmed her forehead. "Oh yes, please, let's all remind me that I'm a self-inverse and too young for the fun stuff," the line said. "I was TRYING to suggest we talk mathematical translations."

"Might be better to leave that to any foreign language experts in the comments," Nat ventured, crossing his arms.

"Actually... by sliding the conversation to the side without rotation, we did perform a translation," Cosine said, smirking.



  1. Linear functions are their own in verses? I knew 1/x was....

    1. Well, the inverse of a linear function will also be linear. It won't necessarily be the same equation, except in some cases. One such case is y=x (hence Lyn's comment), as are any linear functions with a slope of negative one. Makes sense given that an inverse is created by reflecting in the line y=x.

      Sidebar: Still no foreign language experts out there, huh?
