It doesn't specifically say there is one.
Sorry.
You think these lecture notes.
Meant specifically to teach people about the topic.
Asked "What is the error in this equation?"
And there wasn't one?
It doesn't ask "What is
the error in this equation?"
It says "Find
a mistake in equation (2-13)" not "find
the mistake" there is a difference.
What better way to get students to tear into and understand a complicated equation than challenge them to find a mistake in it? The correct response to Problem 2-2 could well be "there isn't one", but you'd be taking your chances saying that without at least some understanding of it.
I couldn't find one, which is what I've said all along.
Well, yes, that's the entire point. You know that there is an error in that specific equation, the writer admits it, and you can't see it.
No, I don't, and no, he doesn't. You're just jumping to a conclusion, that's all.
He could have said "There is a mistake in equation (2-13). Can you find it?" But he doesn't. Why not?
So why do you trust your judgement when it comes to the rest?
Because orbital mechanics makes excellent predictions, so it's reasonable to judge that it's based on facts.
I'm just trying to get a direct answer.
You get it, it's just not the one you want. Instead of assuming I'm evading, ACTUALLY READ WHAT I'M TELLING YOU.
You're telling us you jumped to a conclusion because you interpreted something in a way you wanted it to say, not what it said. This is evident by the way you consistently paraphrase the challenge
incorrectly.
You still haven't confirmed that there
is an error. Do you admit that you haven't found one, so can't know for sure if there is one in there or not?
