Hey the x^2+1 in the blue bracket should be raised to the power of -1......
-
shouldn't the denominator be squared?
-
At 5:12, the expression inside the brackets is being simplified. However, when I multiplied and simplified the expression myself, I got x^2 + 1 + 2x - x^2 - 4x, which equals 1 - 2x, NOT 1 - 4x. What am I doing wrong? :(

Nice video, like any worthwhile subject, the chain rule takes practice.

Low (dhigh) - High(dlow) all over low (times) low....... totally helps to remember the quotient rule... LOL
