# Position in notation.

JDude13
I would like to represent that the position of $$d_n$$ is the same as the position of $$\Lambda_n$$ is at the same position as $$E_n$$. I want to call this position $$x_n$$.

Would I notate it like:
$$x_n=x(d_n)=x(\Lambda_n)=x(E_n)$$
or like:
$$x(x_n)=x(d_n)=x(\Lambda_n)=x(E_n)$$
?

Okay... For simplicity's sake, let's say that each $$x(y_n)$$ value is a distance, in one dimensional space, from a point which I shall call $$x_0$$. Would the former or latter equation be correct?
