▶️ Playlist: https://youtube.com/playlist?list=PLTjLwQcqQzNKTnpE0yhCcXyQrHu5KtGeX ❤️ Unlock everything: https://youtube.com/universaldenker-physics/join 📚 Read lesson: https://en.universaldenker.org/lessons/278 What is a differential equation? How do I solve and classify a differential equation? After the video, you will be able to identify the type of differential equation, whether it is partial (PDE), ordinary (ODE), linear, homogeneous or inhomogeneous, as well as of which order the differential equation is. Then I explain four usefull solving methods: separation of variables, variation of constants, exponential ansatz and the separation ansatz. Video content: 00:00 Why do I need differential equations? 00:30 What is a differential equation? 03:24 Different notations of a differential equation 05:03 What should I do with a differential equation? 06:15 How to identify a differential equation 07:11 What are coupled differential equations? 08:36 Classification: Which DEQ types are there? 15:48 What are DEQ constraints? 18:08 Difference between boundary and initial conditions 20:39 Solving method #1: Separation of variables 23:03 Example: Radioactive Decay law 24:49 Solving method #2: Variation of constants 28:02 Example: RL Circuit 31:33 Solving method #3: Exponential ansatz 37:17 Example: Oscillating Spring 43:21 Solving method #4: Product / Separation ansatz Difficulty of the video: 🧠🧠🧠⚪⚪ Join physics community: Discuss about physics, ask physics questions or leave feedback. 🔗 Discord: https://discord.com/invite/3Btr63fujg About the channel: Here you will find high quality free physics videos for beginners and advanced students.
