In a future video, I'm actually going to prove this. It's a little bit involved. But in this one, we're just going to appreciate that this seems like it is actually true. So right here is the graph of y is equal to the natural log of x. And just to feel good about the statement, let's take the slope, let's try to approximate what the slope of the tangent line is at different points. So let's say right over here, when x is equal to one, what does the slope of the tangent line look like? Well, it looks like here, the slope looks like it is equal, pretty close to being equal to one, which is consistent with this statement.
