About Session 9, Clip 3 on product rule.
At about 6 min. 8 sec into the video, the professor says that he introduced u(v(x+∆x) which he didn't like. However, the formula until then reads (u(x+∆x)u(x))v(x+∆x), so the u in u(v(x+∆x) doesn't concern v(x+∆x) but belongs to (u(x+∆x)u(x)) as is indicated by the brackets.
He later introduced +u(x)v(x+∆x) to cancel for something that actually was not there in the first place.
Although it ends up as it should, I cannot follow the explantion provided. The explanation in the lecture notes seems more logical.
