3.  At 9:08 minutes, please pause the video and look at the values in
x and y; please confirm that these values are as per expectation.
4.  At 9:28 minutes, verify that the lengths of x and y are 126, by
diplaying, verifying and counting.
5.  Find answers to log2(2^5) and log(exp(1)*exp(1)) - explain
6.  Explore the Helptab in RStudio: Change the labels, title, etc.
Hint: try plot(x,y,xlab=''x-axis'')
7.  Copy paste a few examples provided in Help and see what they do
