Learn Facts Quick

Features
Read full description

This is a well-rounded learning application, fully synced with the same functionality as the website, learnfactsquick.com. It can teach you anything using memory techniques such as the major system and number-to-celebrity system to help remember numbers, a major system generator and anagram generator and a mnemonic generator, a complete acrostic(acronyms of names: EG :LEMUR, an animal from Madagascar , = Large Eyed Madagascar Unmistakable Ringtail) system allowing storage and display and editing of a complete database of knowledge which also include mnemonics and peglists(system to remember both index and item of list based on number to mnemonic to list item association). It includes a mnemonics editing tool to edit mnemonics, peglists, and anagrams of lists you want to remember. The best aspect is the new words system. You can custom design it to review new words you enter everyday, then do your reviews quickly everyday with a few button clicks. The idea is that if you review a new word 5 or 6 times with longer and longer intervals, then you will remember it. It is proven that this is how our brains store things into permanent memory. **CHECK OUT learnfactsquick.com

About

Root Locus Plotter

Features
Read full description

Root Locus Plotter is an educational and engineering tool designed to help you visualize and analyze control systems through the Root Locus method. Whether you’re a student learning control theory or an engineer designing feedback systems, this app makes it easy to understand the dynamic behavior of transfer functions and how poles and zeros affect system stability. - Key Features Root Locus visualization: Instantly plot the root locus of any transfer function. Gain and stability analysis: Inspect how system poles move and identify stable or unstable regions. Step response: Visualize the step response with interactive charts and get the analytic expression for transient and steady-state behavior. Support for complex systems: Works with higher-order transfer functions. Compare before and after compensation: View the root locus and step response for both the original plant and the compensated system side by side. - Educational Use Ideal for students studying control systems, feedback theory, and dynamic response. The app provides a clear and intuitive way to connect mathematical analysis with visual intuition β€” a great aid for classroom learning, homework, and lab work. - Engineering Use Engineers and researchers can use Root Locus Plotter to quickly test transfer functions, prototype controller gains, and study how poles and zeros interact under varying parameters. - Get Started Simply enter your transfer function in a clean, intuitive interface, and explore how it behaves as system parameters change. Root Locus Plotter helps you make control theory visual, interactive, and understandable.
