Since I am still learning Python, I designed the logic and guided Microsoft Copilot to generate the code. </p> <p>I just published Version 11 under the GPL-3.0 license!</p> <h3> 🚀 What SemCAS can do right now: </h3> <ul> <li> <strong>SymPy Engine:</strong> Full symbolic math power under the hood.</li> <li> <strong>Going International:</strong> Version 11 adds full English support (previously Dutch only).</li> <li> <strong>Math Features:</strong> Handles algebra, trigonometry (sin, cos, tan), and now limits!</li> <li> <strong>Terminal Friendly:</strong> Uses standard Latin characters (type 'pi' or 'phi' to avoid font crashes).</li> </ul> <p>I am practicing User-Driven Development (UDV), so I am waiting for user feedback before adding the next big feature (like plotting graphs via Matplotlib).</p> <h3> 📦 Check out the project: </h3> <p>You can look at the source code and download the latest release here:<br> <a href="https://github.com/semalewijnse2014-prog/Semcas/releases" rel="noopener noreferrer">https://github.com/semalewijnse2014-prog/Semcas/releases</a></p> <p>I would love to hear your thoughts, tips, and ideas for version 11.1!</p> showdev
