Suat AyözI'll be posting the questions from AMS 2025 Daily Epsilon of Math Calendar daily from now on. I should have started earlier (doing it on Blue sky for some time). Hope it will be of interestHere's the question for April 13th. For those unfamiliar with the calendar, the answer is always the day of the month. Looking for imaginative solutions is the aim. <a href="https://mathstodon.xyz/tags/mathstodon" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#mathstodon</a> <a href="https://mathstodon.xyz/tags/math" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#math</a> <a href="https://mathstodon.xyz/tags/maths" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#maths</a> <a href="https://mathstodon.xyz/tags/mathematics" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#mathematics</a> <a href="https://mathstodon.xyz/tags/MathsToday" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#MathsToday</a>

Pustam | पुस्तम | পুস্তম🇳🇵The Fourier Transform is a mathematical operation that transforms a function of time (or space) into a function of frequency. It decomposes a complex signal into its constituent sinusoidal components, each with a specific frequency, amplitude, and phase. This is particularly useful in many fields, such as signal processing, physics, and engineering, because it allows for analysing the frequency characteristics of signals. The Fourier Transform provides a bridge between the time and frequency domains, enabling the analysis and manipulation of signals in more intuitive and computationally efficient ways. The result of applying a Fourier Transform is often represented as a spectrum, showing how much of each frequency is present in the original signal.\[\Large\boxed{\boxed{\widehat{f}(\xi) = \int_{-\infty}^{\infty} f(x)\ e^{-i 2\pi \xi x}\,\mathrm dx, \quad \forall\xi \in \mathbb{R}.}}\]Inverse Fourier Transform: \[\Large\boxed{\boxed{ f(x) = \int_{-\infty}^{\infty} \widehat f(\xi)\ e^{i 2 \pi \xi x}\,\mathrm d\xi,\quad \forall x \in \mathbb R.}}\] The equation allows us to listen to mp3s today.

Attie GrandeI'm looking for some pointers...I have a vector in 3D space. I want to be able to manipulate its direction based on input pan and tilt angles... Importantly I'd like to be able to give these angles as absolute (i.e: from "up") or relative (i.e: from the current direction).I have a working solution, but I suspect there's a more efficient way to do this. I had a stab with Quaternions, but I couldn't get the tilt to behave like it would on a gimble.Any ideas? 🧮<a href="https://chaos.social/tags/maths" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#maths</a> <a href="https://chaos.social/tags/mathstodon" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#mathstodon</a> <a href="https://chaos.social/tags/embedded" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#embedded</a>

I know that the former is possible on Mathstodon, but I'm trying to figure out if the latter is. It seems like maybe not.

Mg Avaris ClariI have a <a href="https://mastodon.social/tags/math" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#math</a> question for <a href="https://mastodon.social/tags/mathstodon" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#mathstodon</a> if anyone can answer it. I've tried a few times to see if anyone can figure out if this is a thing or if it's coincidence. I've found that for some reason on a standard numpad layout (calculator, phone, etc) a lot of 3 digit sets when added forward and backward equal 3330.
