If ln(x) is 1/x.

But wait! How do we know that the derivative of ln(x) is 1/x? The if y=ln(x), then the derivative of ln(x) at x is the multiplicative inverse of the derivative of e^y at y. (Think about what happens to the slope of the tangent line when you swap the x and y axes.) In other words,
ddxln(x)=(ddyey)−1.ddxln⁡(x)=(ddyey)−1.
But we know that the derivative of e^y is just e^y, so the right-hand side simplifies to
(ey)−1=x−1=1x(ey)−1=x−1=1x.

But wait! How do we know that the derivative of e^y is e^y? Well, that's the definition of the exponential function (or a theorem, if you use a different definition for e)
