I have a function f[t] which is a density function. It has a [0,2] interval and integrates to unity. I convolve f[t] with itself to get g[t]. It has a [0,4] interval and integrates to unity. All is well with that and I understand. BUT, the boundary of g[t] shouild be on the interval [0,4/Sqrt[3]]. This is based upon both simulation and other analyses. At present, the area of the g[t] function on the [4/Sqrt[3], 4] interval accounts for 1.4087% of the area under the curve. Not a "trivial" or "throwaway" amount. Does anyone know of a way to "re-scale" or modify my convolved result g[t] so that all of the resultant area under the curve is on the [0,4/Sqrt[3]] interval? My work is attached. &[Wolfram Notebook][1] [1]: https://www.wolframcloud.com/obj/6f170a6b-733e-4347-9ebe-6dc9a114d84b Patrick McMullen 2026-04-06T17:07:27Z https://community.wolfram.com/groups/-/m/t/3657640 I'd like for this to work in general, with several lists (adj, famadj, etc, which actually look like matrices) of varying sizes. I'd like to not have to define local variables inside the function totaladj, as shown in the code that is commented out. Right now it doesn't work (unless I use the commented out code). Any help would be greatly appreciated. &[Wolfram Notebook][1] [1]: https://www.wolframcloud.com/obj/6e6ed6ad-676d-4659-8b54-8bdbddeae585 Iuval Clejan 2026-03-11T17:45:31Z https://community.wolfram.com/groups/-/m/t/3672532 ![Adiabatic quantum computing: spectral analysis and simulation of a one-qubit system][1] &[Wolfram Notebook][2] [1]: https://community.wolfram.com//c/portal/getImageAttachment?filename=Adiabaticquantumcomputingspectralanalysisandsimulationofaone-qubitsystem.png&userId=20103 [2]: https://www.wolframcloud.com/obj/57c27ccc-c9d9-456a-8535-b7e58d5abb07 Sebastian Rodriguez 2026-03-31T17:00:25Z https://community.wolfram.com/groups/-/m/t/3672541 &[Wolfram Notebook][1] [1]: https://www.wolframcloud.com/obj/7c20d0a3-0451-4f2c-95b5-d4014f395ab4 Rudnei Ramos 2026-03-31T17:01:30Z https://community.wolfram.com/groups/-/m/t/3670655 &[Wolfram Notebook][1] [1]: https://www.wolframcloud.com/obj/1f7da69a-d946-47a1-875a-7ba46bd586e4 Yumin Tian 2026-03-27T06:51:35Z https://community.wolfram.com/groups/-/m/t/3671572 Given the base triangle, the Gergonne triangle is built, which is formed with the three tangential poiints of the circle inscribed with each side of the base triangle. Then the sides of both triangles are prolonged until they intersect with three points D', E' and F' which are colineal because they are on the Gergonne line and are known as Nobbs points. &[Wolfram Notebook][1] [1]: https://www.wolframcloud.com/obj/831ca97a-405b-4145-94bf-e7c8e46609d3 Alejandro Latorre Chirot 2026-03-29T15:10:57Z https://community.wolfram.com/groups/-/m/t/3666521 &[Wolfram Notebook][1] [1]: https://www.wolframcloud.com/obj/f11d23b7-da4b-4d24-b10f-dc65abfedc9c Bruno Tenorio 2026-03-20T01:11:50Z https://community.wolfram.com/groups/-/m/t/3661100 ![Pi Day 2026: formulas, series, and plots for π][1] &[Wolfram Notebook][2] [1]: https://community.wolfram.com//c/portal/getImageAttachment?filename=PiDay2026formulas,series,andplotsforPi.png&userId=20103 [2]: https://www.wolframcloud.com/obj/57c23bcf-fe04-4342-82a2-00a93c274641 Anton Antonov 2026-03-15T03:11:40Z https://community.wolfram.com/groups/-/m/t/3662295 It seems the symbolic integration in Mathematica 14.3 has problems with complex path integrals.

Join me and fellow food and nutrition enthusiasts to learn how to compute, analyze and visualize data from Wolfram Language's built-in knowledgebase of foods. Our topics for the study group include easy-to-use nutrition data retrieval and analysis tools, nutrient comparison plots and visualizations, statistical analysis of nutrition data, recipe management with LLMs, and food chemistry and physics with curated data and built-in formulas. No prior Wolfram Language experience is required. Please feel free to use this thread to collaborate and share ideas, materials and links to other resources with fellow learners. **Dates** February 23-27, 2026 (Monday through Friday), 11am-12pm CT (5-6pm GMT) > [**REGISTER HERE**][1] I hope to see you there! ![enter image description here][2] [1]: https://www.bigmarker.com/series/computational-food-and-nutrition-wsg75/series_details?utm_bmcr_source=community [2]: https://community.wolfram.com//c/portal/getImageAttachment?filename=4505hero.png&userId=20103 Gay Wilson 2026-01-06T00:18:12Z https://community.wolfram.com/groups/-/m/t/3649769 ![Special Functions: A Computational Approach now available in Wolfram Notebook format][1] &[Wolfram Notebook][2] [1]: https://community.wolfram.com//c/portal/getImageAttachment?filename=SpecialFunctionsAComputationalApproachnowavailableinWolframNotebookformat.png&userId=20103 [2]: https://www.wolframcloud.com/obj/4a2dc2d7-e361-4e5e-9336-8922f7cde0a3 Tigran Ishkhanyan 2026-03-05T13:10:41Z https://community.wolfram.com/groups/-/m/t/3647051 [![The entropy bagel: complex roots of Littlewood polynomials][1]][1] &[Wolfram Notebook][2] [1]: https://community.wolfram.com//c/portal/getImageAttachment?filename=_test.jpg&userId=11733 [2]: https://www.wolframcloud.com/obj/97dc0591-1fe8-45a9-9cf7-8074051c6b12 Ed Pegg 2026-02-27T17:34:59Z
