Great resource, but the first example on slide 4 is incorrect, missing a power of 3 (chain rule)

When I click on "Click for proof" it doesn't seem to work - it simply goes on to next slide

In this powerpoint it says that the differential identities for trig functions such as tan(x), cosec(x), sec(x) and cot(x) are NOT given in the formula booklet, but they in fact ARE PROVIDED. That being said, it is correct to say it is handy to learn them.
