For the lynx data (“LYNX.txt” from the Exercises folder):

i. Plot the original data versus time. Does it appear that the minima are curved/rounded and the maxima are sharply peaked?

ii. Plot the data (versus time) with both the logarithmic transformation and the square-root transformation and examine whether either (or both) transformation makes the data more amenable to a trigonometric analysis.
