I follow you up until you bring A into the equation. I'm not quite sure why you do that because I really wasn't taught anything about that.
I should say that this question here is from Calculus II, and that we've only just gone into the intro to Differential Equations, nothing serious. Is there another way to do it without introducing the A? What's this modulus?
So this is what you were getting at basically? If not where did I go wrong?
Plug back in:
The only differences between our answers is a minus sign:
I should say that I have to then compare or do % error between some values in Euler's Rule, which I already did. And Your answer is the correct one. Can anyone tell me how I got an extra minus sign in there? Or perhaps my value for C I obtained is wrong?
