CALCULUS (MA1CANU)

Python Programming Assignment

This assignment counts for 20% of the total marks of this module. Full marks for this

assignment can be gained from complete answers to ALL questions and submitting the

Python script .py for each questions on Blackboard system before 14:00, 20th

December 2024 (Friday).

Submission Instructions

For each of the following questions

 Put your Python script file into an individual script with the file name

PS_Assgn_Q(n)_StudentID.py using the Save As option under the File menu on

the editor window.

Where `n' should be the question number (i.e. one of 1, 2, 3, 4) together with any

subpart (e.g. 3a), and `StudentID' is your 8-digit Student ID number.

 At the beginning of each Python script, add a comment line to state `This is the

script for Q (n) of Assignment' where 'n' is the question number.

 For each question involving a graph plot, save each graph as a .png file

PS_Assgn_Q(n)_StudentID.png using the Save option on the plot window.

 All graphs must include your student number in the title of the graph.

 All scripts and .png/.jpg files must be uploaded together as one submission to

Blackboard under Assessment. If multiple submissions are received only your final

submission will be marked. N.B. resubmission deletes all previous submissions so

ALL files must be re-uploaded.

 Scripts submitted in any form other than a .py file will not be

marked.

Exercises

When answering the following questions use the principle of top-down design to design

your algorithm before encoding it. (You do not need to submit proof of this on this occasion

but in using it you should make your scripts both accurate and efficient, as well as saving

yourself time.) You might also find it useful to review lectures and practical examples.

Note that you should only use Python commands and built-in functions covered in lectures

and practicals to answer these exercises unless you are directed otherwise. 1. Write a Python script that can print the following actions for a matrix

2. Write a Python script of the matrix

to print the transpose, inverse, determinant, trace, singular values and   3

4. Write a Python script file to print the solution of the equation

6. Consider the series for the function is given by

a. Write a function my_   _(  ) that takes values over the interval    = 0 to 5 as input and

returns the approximate value of   (  ). [4 marks]

b. Use a script to apply the function my_   _(  ) developed in (a) to plot the sum   (  ) versus

  using a for loop for    = 0 to 5. Label the axes appropriately and use your UoR student

Id number as the title for the plot and submit .png/.jpeg file of output. [4 marks]

c. Print a column vector    by extracting the elements from the third column of array   .

[2 marks]

Print the cross-product function    =    ×   . [2 marks]

e. Print the vector   =    +   . [2 marks]

Print a row vector B by extracting the elements from the second row of array   .

[2 marks]

a. Print a matrix A . [2 marks]

5. Define the variables    = 0.4,    =0.8 and then use them to create a Python script file

and print a row vector (assign it to a variable named e) that has the elements:[12 marks]

3. Consider

i. Write a function my_ that takes values of as input and returns the approximate

value of   . [2 marks]

ii . Use a script of the function my_ developed in (i) to use for loop to calculate and

print the solution. [4 marks]

7. Use for loops to calculate and print the sum of the following quantities [10 marks]

Hint: Consider (−1)

. (answer: 0.71432)

Also, plot the catacaustic of the asteroid on the same plot over the same range for  :

Make sure to use enough points to create smooth curves. Provide a plot title, labels

for the axes, and a legend for the two curves and submit a .png/.jpeg file output.

9. Create a Python script file to generate a surface mesh plot of the following function:

Make the step sizes for the    and    directions the following: . Use your

student ID number as a plot title and labels the axes appropriately [8 marks]

10. A system of linear equations is given by:

Create a Python script file to solve this system by implementing the following steps:

Use the elimination method to solve it and use the error command to report the error

if it occurs.

Display the solution if a unique solution exists.

If the unique solution exists, plot the lines representing the equations on the same

graph and mark the intersection point as the solution.

If a unique solution doesn't exist, provide an appropriate message indicating the

case (e.g., parallel lines, co-incident lines).

Apply your Python script to the system

If the solution exists and is plotted use your UoR Student ID number as the title for

the plot and also submit a .png/.jpeg file along with your script. [6 marks]

order linear differential equation:

a. Write a the system of equations system_of_equation(t,a) that takes values of , as

input and returns . [2 marks]
