Radu Mariescu-Istodor | Learn Trigonometry with JavaScript @Radu | Uploaded 1 year ago | Updated 1 hour ago
We study trigonometry by implementing an interactive tool in JavaScript. We learn several trigonometrical functions like the sine, cosine and tangent (sin, cos, tan) and their inverse functions: the arcsine, arccosine and arctangent (asin, acos, atan). We define these functions using a right angle triangle at first and then extend the definitions using the unit circle.
We practice these functions using JavaScript in a way that hopefully makes them more clear and useful. Check out more videos like this:

Welcome to Lesson 9 of the Understanding AI course, where Ill guide you through the exciting process of creating procedurally generated racing game sounds using JavaScript and the WebAudioAPI. In this video, Ill teach you how to generate sound from scratch, starting with a simple beeping noise that we can play at different frequencies. Well then dive into the intricacies of creating dynamic engine noises for our racing game.
These procedurally generated sounds arent limited to our project alone – you can use them in any of your creative endeavors. However, Ill demonstrate how to seamlessly integrate these sounds into our racing game with self-driving cars. Imagine the beeps enhancing your countdown timer and the engine noise dynamically changing based on the cars actions in the game.
So, get ready for some sound advice! Well explore the world of sound generation in JavaScript, adding an auditory dimension to our gaming experience. Join me in this immersive lesson, and lets make our racing game truly come to life with unique, procedurally generated sounds. Dont forget to like, share, and subscribe for more lessons on AI, game development, and creative sound design!

Welcome to the course where we build a self-driving car simulation in a virtual world using HTML, CSS and JavaScript. In this video well learn a critical phase of our UI development journey! So far, weve been saving our graph data in local storage and regenerating it when the page loads. But in this way we lose those markings, cant store multiple worlds, and the random appearance of trees might not be something you want.
Moreover, as we move into working with real-world data, youll realize that drawing such extensive graphs manually isnt practical. Thats why its crucial to explore a more efficient approach: storing information in actual world files that can be loaded when needed! 🌍
Lets learn about data persistence and discover how to save and load your graph efficiently, preserving all your hard work and making your UI development experience smoother.
Have Fun! :-)
