For figure (1) , three part i.e. part-I-III equation has been used to plot. I am able to generate the figure (1) plot with given equation successfully. Part -IV equation shows the some modification of part-I and part-II equations and figure (2) plot should be according to this modification. Figure (2) should be somewhat similiar to figure (1), but i am getting totally different result. Can you please look into the code how it can be corrected??
Thank you
