Description
Assignment description:
This assignment will be worth 7% of the final grade.
You should write your code for each question in a .py file (please name it using the
question name, e.g. q1.py). Please pack all your .py files into a single .zip file, name it
using your student ID (e.g. if your student ID is 123456, then the file should be named
as 123456.zip), and then submit the .zip file via Moodle.
Please also write a text file, which provide the details about how to run your code for
each question. The text file should be included in the .zip file as well.
Please note that, the teaching assistant may ask you to explain the meaning of your
program, to ensure that the codes are indeed written by yourself. Please also note
that we may check whether your program is too similar to your fellow students’ code
using Moodle.
This assignment is due on 5:00PM, 11 March (Sunday). For each day of late submission,
you will lose 10% of your mark in this assignment. If you submit more than three days
later than the deadline, you will receive zero in this assignment.
Question 1 (10% of this assignment): Suppose you want to deposit a certain amount
of money into a savings account with a fixed annual interest rate. What amount do
you need to deposit in order to have $5,000 in the account after three years? The
initial deposit amount can be obtained using the following formula:
???????????????????? =
?????????????????
(1 + ??????????????????)
?????????????
Write a program that prompts the user to enter final account value, annual interest
rate in percent, and the number of years, and displays the initial deposit amount. A
sample run of your program:
Question 2 (15% of this assignment): Write a program that prompts the user to enter
an integer and displays the number in reverse order. Here is a sample run:
Question 3 (15% of this assignment): Write a program to allow a user to input a
number m, and then use a while loop to find the smallest integer n such that n
2
is
greater than m. For example, if the user inputs m = 10, your program should output n
= 4.
Question 4 (15% of this assignment): Write a program to allow a user to input a
number N, and print a table with N rows and 3 columns. In the mth row, your program
should output three numbers: m, m+1, and mm+1. For example, when the user inputs
N = 5, your program should output the following:
Your program should be robust enough to handle the possible improper inputs (e.g.
the user inputs a negative N).
Question 5 (20% of this assignment): Write a program to allow a user to input an
integer N, and print all the prime numbers which are smaller than N. For example,
when the user inputs N = 10, your program should output
Your program should output at most 8 prime numbers in each line. Your program
should also be robust enough to handle the possible improper inputs (e.g. the user
inputs a string).
Question 6 (25% of this assignment): Given a function f(x), and a real interval [a, b],
the numerical integration of f(x) over interval [a, b] can be calculated as:
∫ ?(?)?? ≈ ∑
?−?
?
?
?=1 ?(? +
(?−?)
?
× (? − 1/2))
?
?
(1)
In equation (1), n represents the number of sub-intervals into which the interval [a, b]
will be divided; and it controls the accuracy of numerical integration.
Write a program to allow the user to specify a trigonometric function f (f can only be
sin, cos or tan), and input the interval end points a, b and number of sub-intervals n.
Your program should then calculate the numerical integration of f over [a, b] using
equation (1), and output the result. Your program should be robust enough to handle
possible improper inputs (e.g. the user inputs a floating point number as n).
Python has built-in trigonometric functions. To call them, use the following statement
in your program to import them from the math package:
You can then invoke the trigonometric functions like the following examples:
