I have a function given implicitly, you know. X og Y on both sides. Than it says, assume y=y(x). That's fine. And find y'(0), that I should be able to do. But what about y''(0)? How do you treat the dy/dx parts when taking the second derivative?
Edit: I would also like to follow the tip in the book, that says when I'm after actual values. We can just insert the value instead solving for dy/dx.
