Daniil Baturin<p>In our high school math textbook, there were formulae for converting sums of trigonometric functions to products. We were tested of their knowledge. I hated them because there was no imaginable practical use for them.<br>One time, my late grandmother who was a chemical engineer, found an artifact of her young days in a cabinet — a slide rule.<br>When I came to visit her, she showed me that thing and offered to show me how it was used. "Look, it's trivial to multiply, but to add... let me show you, there's a trick for that".<br>Then the true purpose of the useless formulae clicked. They were there to help people make their lives simpler in the slide rule era. And then, no one thought to remove them from the textbook and it was reprinted with those out-of-context artifacts still in.</p><p><a href="https://functional.cafe/tags/math" class="mention hashtag" rel="nofollow noopener" target="_blank">#<span>math</span></a> <a href="https://functional.cafe/tags/trigonometry" class="mention hashtag" rel="nofollow noopener" target="_blank">#<span>trigonometry</span></a> <a href="https://functional.cafe/tags/sliderule" class="mention hashtag" rel="nofollow noopener" target="_blank">#<span>sliderule</span></a></p>

When you strictly replace your available var types with vectors, a whole new world of physical simulation opens up.

You'll limp along, by mapping magnitudes to familiar constants, but you will outgrow that cringe.

A world where partial differential equations roll off your fingertips, like butter and syrup roll off of a stack of pancakes.

Learn to code in 3 dimensions.

Breathe #trigonometry.

Wow, a riveting tale of sunset geometry 🌅📐—because who doesn't want to spend their evening calculating the Earth's radius with a single sunset photo? 🤓🔍 Clearly, classical #trigonometry just wasn't making math nerdy enough, so let's sprinkle in some Geometric Algebra for extra pizzazz. 🎉
