The aim of this practical is to introduce use the 3rd party Python packages matplotlib, numpy and sympy to make plots and solve simple problems. Include all code and plots in your submission. Question 1. [10] Question 1.1. Use matplotlib to make a scatter plot of the (x, y)-points in the provided dataset dataset0. txt. (You do not need to write out the dataset in your submission). Question 1.2. Define po := 0, p1 := 1 and pn := 2pn-1 + Pn-2 for n = 2, 3.... Use a list comprehension to generate the dataset {(n, Pn) : n = 0, 1, 2, ..., 20 }. Use matplotlib to make a scatter plot of the (x, y)-points in this dataset. Question 1.3. Use numpy and matplotlib to make line plots of the functions f and g as defined below on the same set of axes. . f : [-20, 10] - R is defined as f(x) := x sin(x - 5) for x E [-20, 10]. . g : [-20, 10] - R is defined as g(x) := arctan(x) for x E [-20, 10]
