Hi,
I'm hitting the wall to solve this problem as title, show that -ln(x-sqrt(x^2-1)) = ln(x+sqrt(x^2-1)). This is problem from my precalculus text book by jame stewart in logarithm function section.
I really have no idea why they are identical graph. I can clearly see that they are same in graph calculator and put arbitrary number in it, getting same number. But why? Can anyone help me understand what's the rationale behind it?
