In this video I calculate two limits involving ln, which are surprisingly related. The squeeze theorem and Riemann sums make a special appearance. Enjoy!

A kite is placed in a square, can you figure out one of its angles? I made a video for this "impossibly hard" problem from a New Zealand maths exam. But it turned out my proof had a flaw, which some of you pointed out in the comments! It turns out the problem…
