# A question about composite functions watch

1. (Original post by generalebriety)
You're not thinking at all. Look at how the inductive step takes us from n = 1 to n = 2. I can't give you a bigger hint than that.
Okay, I think I understand hat you mean now.

So induction step is this. n=1, then and x_1=x_1 and and x_2=x_2. But, then all you know is that x_1=x_1 and x_2=x_2, so you can't deduce x_1=x_2.

So induction fails on n=2.

Correct.

Correct
Yeah, thanks for that. I think that got rid off a few problems I have with induction.

Sorry, I guess you wouldn't be able to conclude that x_1=x_2 in the first place.
