Had trouble remembering the big SI prefixes, especially the new ones. Kilo/Mega/Giga/Tera are old school. Peta you see sometimes. Then it gets easy, why argue? E Z Y R Q

New Post: betterexplained.com/articles… If the exponential function is water, the hyperbolic functions (cosh and sinh) are hydrogen and oxygen. They're the technical, rarely-discussed parts that combine into a famous whole.

Analogy in progress: Fourier Transform: Given a smoothie, get a recipe. LaPlace Transform: Given a smoothie, get a recipe *book*. The FT assumes perfect ingredients. The LT lets you specify how old your ingredients are. The FT is the first page of the book.

The LaPlace transform is "overdetermined". You don't need the entire book, you can use the recipe from any page. The LaPlace transform is mostly used to see how the recipes change over time. Do weird things happen to specific ingredients as we flip through the pages?

Work in progress. Integral of sin(x) is better visualized as total horizontal change between endpoints, vs a generic "area under the curve"

Gotcha: remember that sine isn't inherently "vertical". It's just a percentage. If you rotate your triangle, it determines the horizontal distance traveled as you change your angle.

I have very few equations on my pages in part because I don't know how to present them. @betterexplained uses color for equations (betterexplained.com/articles…); @ch402 uses layout for equations (github.com/distillpub/post--…); so I wanted to try both together 🧐
