Assignment 1
Draw two plots overlaid upon each other, with the first plot being a parabola of the form y = 4(x ^ 2) and the second being a straight line of the form y = 2x + 3 in the interval -5 to 5. Use colors to differentiate between the plots and use legends to indicate what each plot is doing. 

Assignment 2
Draw a line of the form y = x as one figure and another line of the form y = 2x + 3. Switch back to the first figure,annotate the x and y intercepts. Now switch to the second figure and annotate its x and y intercepts. Save each of them. 

Assignment 3
We know that the Pressure, Volume and Temperatures are held by the equation PV = nRT where nR is a constant. Let us assume nR =0.01 Joules/Kelvin and T = 200K. V can be in the range from 21cc to 100cc. Draw two different plots as subplots, one being the Pressure versus Volume plot and the other being Pressure versus Temperature plot.
