Add equations to 19.2 Ex 4. ( #749 )
...
The question asks:
> Follow <http://nicercode.github.io/intro/writing-functions.html > to write your own functions to compute the variance and skew of a numeric vector.
However, the math on that page no longer renders.
Directly include the skew and variance equations in the question.

I think there is a typo in wt_mean because if it's a weighted mean of x with weights w it should be sum(x * w) / sum(w)

I also changed the order of words in a sentence, but that might be a matter of style.

Take care!
* Determinant changed to determine
For some reason, the Travis CI didn't build when I changed the last file. I'm trying again, hope it isn't a bother (is there a term for spamming a github repo?)

Functions.Rmd: some words on identical()
...
Adds discussion of `identical()` function to `if` section.
I, personally, find identical() to be useful, but I can see that it does not add aesthetic value to the code.
(BTW, really enjoying seeing this book come together!)
