Today I wrote on #Python #Functions because that is what I read about. I'm learning as I write the series so I will probably make mistakes or do things less then better, but be kind I'm trying :)

The New “if()” Function in CSS Has Landed in the Latest Chrome, by @amitmerchant.bsky.social:

If a function has a neutral element, then applying it to zero arguments will return it. If a function has no neutral element, calling it with zero arguments is an error.
E.g.:
(sin) ==> error
(-) ==> error
(- 1) ==> -1
(- 1 1) ==> 0
(- 10 2 3) ==> 5

Procedural landscape generation:
I made a "small" #Shadertoy #GLSL thingy that can generate implicit functions with equal thickness (Thanks for the magic of dual numbers). Link: https://www.shadertoy.com/view/wcyGRw
It features a large set of functions:
- Elementary operations
> +, -, *, /
- Exponentials
> exp, log
- Powers and roots
> sqrt, cbrt, pow (TODO)
- Sign related
> step, sgn, ramp, abs
Rounding
> floor, round, ceil
Trigonometry:
> sin, cos, tan, sec, csc, cot,
Hyperbolics:
> sinh, cosh, tanh, sech, csch, coth
Inverse trigonometry:
> asin, acos, atan, asec, acsc, acot
Inverse hyperbolics
> asinh, acosh, atanh, asech, acsch, acoth
It only has some bugs with functions that have poles. For example y=tan(x) produces straight lines at each pole.

How to Have the Browser Pick a Contrasting Color in CSS, by @jensimmons (@webkit):
Integrals of inverse functions!
Proof without words (see image; credit: Jonathan Steinbuch, CC BY-SA 3.0, via Wikimedia Commons)...
For any montonic and invertible function \(f(x)\) in the interval \([a,b]\):
\[\displaystyle\int_a^bf(x)~ \mathrm dx+\int_{f(a)=c}^{f(b)=d}f^{-1}(x)~\mathrm dx=b\cdot f(b)-a\cdot f(a)=bd-ac\]
If \(F\) is an antiderivative of \(f\), then the antiderivatives of \(f^{-1}\) are:
\[\boxed{\displaystyle\int f^{-1}(y)~\mathrm dy=yf^{-1}(y)-F\circ f^{-1}(y)+C}\]
where \(C\) is an arbitrary constant (of integration), and \(\circ\) is the composition operator (function composition).
For example:
\[\begin{align*}\displaystyle\int \sin^{-1}(y) \, \mathrm dy &= y\sin^{-1}(y) - (-\cos(\sin^{-1}(y)))+C\\ &=y\sin^{-1}(y)+\sqrt{1-y^2}+C\end{align*}\]
\[\displaystyle\int \ln(y) \, dy = y\ln(y)-\exp(\ln(y)) + C= y\ln(y)-y + C.\]
