<div class="math">\frac{cos(h)-1}{h}\cdot \frac{cos(h)+1}{cos(h)+1}</div>

<div class="math">=\frac{cos^2(h)-1}{h(cos(h)+1)} = \frac{-sin(h)}{h(cos(h)+1)}</div>

The bottom will still approach zero.

Just look at proof wiki and be done with it:

It's ln(x),
But Wolfram|Alpha specifically says:
"log(x) is the natural log" in the corner of the solution

Learn to look.
