Learn Plotting - All univeristy Questions Submit before 10pm on 13th sep 2026. 1.Plot the function   y = 3x^2 for −1 ≤ x ≤ 3   as a continuous line. Include enough points so thatthe curve you plot appears smooth. Label the axes x and y 2.Plot the functions sin x and cos x vs x on the same plot with x going from −π to π. Make sure the limits of the x-axis do not extend beyond the limits of the data. Plot sin x in the color orange and cos x in the color green and include a legend to label the two curves. Place the legend within the plot, but such that it does not cover either of the sine or cosine traces. Draw thin gray lines behind the curves, one horizontal at y = 0 and the other vertical at x = 0 3.Explain semi-log plots and log-log plots along with the functions used in creating such plots. 4.Write the specific purpose of functions used in plotting: i) plot( ) ii) legend( ) iii. title( ) 5.Create an array in the range 1 to 20 with values 1.25 apart. Another array contains th...

 Here, we will learn a more advanced syntax that harnesses the full power of matplotlib. It gives the user more options and greater control. import numpy as np import matplotlib.pyplot as plt # Define the sinc function, with output for x=0 # defined as a special case to avoid division by zero def s(x):      a = np.where(x == 0., 1., np.sin(x)/x)      return a x=np.arange(0., 10., 0.1) y=np.exp(x) t=np.linspace(-15., 15., 150) z=s(t) # create a figure window fig = plt.figure(figsize=(9, 7)) # subplot: linear plot of exponential ax1 = fig.add_subplot(2, 2, 1) ax1.plot(x, y, 'C0') ax1.set_xlabel('time (ms)') ax1.set_ylabel('distance (mm)') ax1.set_title('exponential') #subplot: semi-log plot of exponential ax2 = fig.add_subplot(2, 2, 2) ax2.plot(x, y, 'C2') ax2.set_yscale('log') # ax2.semilogy(x, y, 'C2') # same as 2 previous lines ax2.set_xlabel('time (ms)') ax2.set_ylabel('distance (mm)') ax2.set_title('exponent...

matplotlib can display mathematical formulas, Greek letters, and mathematical symbols using a math rendering module known as mathtext. The mathtext module parses a subset of Donald Knuth’s TEX mathematical typesetting language, and provides basic mathematical typesetting without any software other than matplotlib. If, in addition, you have TEX (and/or LATEX) as a separate standalone program (such as MacTex [TexShop] or MiKTeX), then you can do even more. In what follows we will assume that you are using the native matplotlib mathtext, but will make a few comments applicable to those who have a separate installation of LATEX. matplotlib’s mathtext can display Greek letters and mathematical symbols using the syntax of TEX. If you are familiar with TEX or LATEX, you have hardly anything to learn. Even if you are not familiar with them, the syntax is simple enough that you can employ it in most cases without too much effort.You designate text as mathtext by placing dollar signs (dollar) ...
