Differential equations section is very hard to work through

I've started learning DE's with a variety of resources. I've used Khan academy, a textbook, and various youtubers like professor Leonard, blackpenredpen, and patrickjmt. Brilliant is the absolute worst. It takes everything that people hate about their textbook and somehow makes it even harder to digest. If you look at any of the youtubers I mentioned, their comments are full of people saying how terrible their teacher/textbook is and how great it is to find someone who explains the topic in plain English that is easy to understand. Textbooks look great to academics who have a Ph.D and want to explain every nuance in full detail, but to an amateur learning it for the first time this is hard to grasp and quickly becomes frustrating.

Brilliant somehow makes it even worse. Explanations are sometimes a full page of equations without a single number in them. Yeah I know this looks great to someone with a math degree but most of the people here don't have one and just want something to help them study that is easy to understand. The explanations feel lazy. I know it's hard to take a complex topic and make it easy to understand but that's sort of what people are paying for isn't it? I really had high hopes for this but I'm going over material I've already learned using other resources and brilliant somehow makes it confusing and aggravating.

This discussion board is a place to discuss our Daily Challenges and the math and science related to those challenges. Explanations are more than just a solution — they should explain the steps and thinking strategies that you used to obtain the solution. Comments should further the discussion of math and science.

When posting on Brilliant:

  • Use the emojis to react to an explanation, whether you're congratulating a job well done , or just really confused .
  • Ask specific questions about the challenge or the steps in somebody's explanation. Well-posed questions can add a lot to the discussion, but posting "I don't understand!" doesn't help anyone.
  • Try to contribute something new to the discussion, whether it is an extension, generalization or other idea related to the challenge.
  • Stay on topic — we're all here to learn more about math and science, not to hear about your favorite get-rich-quick scheme or current world events.
