grayson Posted September 4, 2023 Share Posted September 4, 2023 I am not IN college, but I am watching college classes online on YouTube. (MIT ones, to be exact). They brought up linear differential equations. I don't even know how to solve any I come across. I know algebra and calculus but I know nothing about whatever that is. Can someone help me?

Bufofrog Posted September 4, 2023 Share Posted September 4, 2023 Teaching differential equations on a science forum is not doable. There are online courses but keep in mind you must do the homework to get the full gist of the class. Link to comment Share on other sites More sharing options...

I am using the "cheat code" and watching it on youtube. I am too young to be in the class yet If you wan't the link to the video, I will give it.

studiot Posted September 4, 2023 Share Posted September 4, 2023 Can you solve this equation x2 = 9 I hope so because my next question is what is x2 ? My answer here is that is it a function of x f(x) = x2. There are lots of possible equations involving functions of x. A function is an expression or formula that tells us to do something with x. In this case to square it. Some are useles, boring or otherwise uninteresting. Derivatives are functions of x. So we can write equations involving the function that tells us to differentiate x. A very simple one is dy/dx = 5. Solving it tells us we have a straight line with a slope of 5 Link to comment Share on other sites More sharing options...
