Beautiful Trigonometry vs Get Good

Trigonometry doesn’t have to be confusing. When my daughter first met sine and cosine in school, she asked, “Why do we even need this?” We tried formulas, practice sheets, even flashcards — but it still felt like memorizing rules without meaning. So I built a way to make it visible. With sliders, color, and motion, she could see how angles and sides connect — how triangles breathe, how waves emerge, and how every formula has a shape behind it. That small experiment became Beautiful Trigonometry — an interactive app that turns math from abstract to intuitive. Instead of memorising, explore. Move a slider, rotate a triangle, or trace the unit circle — and suddenly, sine, cosine, and tangent make sense. You’ll discover how to: - Understand how angles and sides connect - See how triangles and graphs reflect each other - Build intuition with the unit circle - Learn faster using animations and instant feedback Free to explore: - Acute Angle Trigonometry: sine, cosine, and tangent made visual - Full Circle Functions: understand sine and cosine across 360° - Triangle Area: learn the sine area formula interactively - Law of Cosines: see it work step by step Upgrade to PRO and unlock: - Graphs of all trig functions: sine, cosine, tangent, cotangent, secant, cosecant - Trig Identities & Formulas: a complete reference Perfect for - Students who want trigonometry to finally click - Teachers and tutors explaining visually - Anyone who loves learning through discovery You won’t just study trigonometry — you’ll feel it click. Part of the Beautiful Math series. Learn visually. Understand deeply. Move ahead.

Get Good: Linux helps you learn Linux by doing. Instead of memorizing commands, you follow a clear progression: learn the core concepts, practice one idea at a time, and apply your knowledge through short, hands-on terminal missions. The app is designed to stay approachable for beginners while still giving you room to grow into more advanced command-line skills. Inside the app, you can: Work through guided lessons on navigation, files, search, and permissions Practice drills to reinforce command usage and syntax Use a terminal-style interface to make commands feel real and concrete Study patterns, examples, and common mistakes Review and create custom flashcards Complete mission-style exercises that apply commands in context Track progress, streaks, mastery, and badges Get Good: Linux is built for focused, structured practice in short sessions. It’s ideal for beginners starting from scratch, as well as developers and technical learners looking to reinforce fundamentals. Topics include: Navigating directories and finding your location Listing files (including hidden files) Creating files and folders Reading file contents Searching with grep Understanding permissions and numeric modes The approach is simple: start with the smallest correct command, then build toward more advanced usage as needed. If you want a practical, approachable way to build Linux confidence one command at a time, Get Good: Linux is built for that.
