🚀 Oh, look! Another riveting exploration of mathematical function #optimization that will surely redefine human existence. Apparently, the key to faster asin() was hiding in plain sight, and we bet it was right next to the cure for world hunger. 🙄 Let's all just take a moment to thank the gods of #trigonometry for this groundbreaking revelation. 🥳

Why doesn't #Mathematica simplify sinh(arccosh(x))? Because apparently, it takes a PhD in #Trigonometry, a magnifying glass, and a deep existential crisis to venture into that rabbit hole. 🤔🔍 Just when you thought it was all about cosines and sines, hyperbolics crash the party and demand their own dissertation. 📚🎉

Now the music is in its flow, so I have time to come back to drawing and generative arts.

Today, I picked sine and cosine and combined them with some alpha values. I have many results and I will post some others of this session, too.

But here's a circle with a sine wave as the radius and this looped while changing radius and phase.

It's all coded by myself. I used mathematical functions to create this piece of art. And no AI.

#30 Its not a bug, its a feature.

To explain to you, it's not a bug that there are two dots and an arc, it's a feature. And yes, some fun at the end of Genuary has to be included.

When I made the first monthly challenges I was stressed and focus on good results. But as soon as I lifted fun to the top leader I learned much more and developed during every challenge. Last october I learned sculpting from scratch during Sculptober. So, let us smile together today that we produced awesome creations.

What do you smile about today?

How would you create such a sliding glow effect on `:hover`? Trivial with `corner-shape`, but what about making it work cross-browser now?

Think about it, then check my solution on @codepen https://codepen.io/thebabydino/pen/EayVXKj

Detailed explanation of the Maths behind (with drawings) on Ko-fi/ Patreon. This way you get to both become smarter and support my work so I can continue coding.

A few years ago I learned about the concept of antiperiodicity. For example, the function \( f(x) = \sin x\) is \(\pi\)-antiperiodic because \( \sin (x+\pi)=-\sin x\).

The fact that \( \sin x\) and \( \cos x\) are both \(\pi\)-antiperiodic explains a lot! For example, this explains why \( \tan x\) is \(\pi\)-periodic even though \( \sin x\) and \( \cos x\) are \(2\pi\)-periodic:

\[ \tan (x+\pi)=\frac{\sin (x+\pi)}{\cos (x+\pi)}=\frac{-\sin x}{-\cos x}=\frac{\sin x}{\cos x}\]
which of course is just \(\tan x\).

Similarly, it explains why \( \sin^2x \) and \( \cos^2x \) are \(\pi\)-periodic.

It even explains why rose curves in the polar plane of the form \( r = \sin(n\theta)\) sometimes have n petals and sometimes have 2n petals! (Secret: they *always* have 2n petals).

Hype for the Future 68J: The Derivatives of the Different Trigonometric Functions?

Overview

While novaTopFlex would like to explain the derivatives and integrals of the different trigonometric functions, LaTeX would be required in order to correctly interpret the underlying situation.

One of my earliest #CSS #3D demos on @codepen: how to (de)construct a dodecahedron https://codepen.io/thebabydino/pen/ALQVQe

A dodecahedron is one of the 5 regular polyhedra = made up of only identical regular polygon faces. Regular polygons have all edge lengths and vertex angles equal.
