QUESTION 1: Using the built-in function "polyder", write a local function called "polyderivative" that will return the coefficients of the nth derivative of a polynomial. The function will receive 2 input arguments: the coefficients of the original polynomial and the degree of differentiation (n). The function will also display an error message if the degree of differentiation is less than or equal to zero. Start with the function definition shown below. function [y] = polyderivative (x,n) % Y = POLYDERIVATIVE (X, N) returns the coefficients of the nth derivative of % a polynomial end For example: ans = x = [1 3 2 2]; polyderivative (x,2) 6 6

It is estimated that a restaurant's tip box accumulates twice as much as the previous day. Write the function with the main () function that takes the number of days as a parameter and returns the total tip amount on the day entered in the restaurant with a 10-TL tip on the first day. Sample Work: Enter the number of days: 4 --------------------------------- Total estimated stake in the box: 150.00 -TL in c
Write a function grade2number that takes a student's letter grade (A, B, C, D, F) as a char and returns the corresponding numerical score in the GPA (4.0, 3.0, 2.0, 1.0, 0.0). You should handle the case when the student enters an invalid character (e.g. G) by returning -1.0. Use a switch statement. The function will be called as in the code below. Γράψτε μία συνάρτησης grade2number> που παίρνει τον βαθμό ενός μαθητή ( A, B , C , D, F) ως χαρακτήρα (char) και επιστρέφει την αντίστοιχη αριθμητική βαθμολογία GPA ( 4.0, 3.0, 2.0, 1.0, 0.0 ) . Θα πρέπει να χειριστείτε την περίπτωση που ο μαθητής εισάγει μη έγκυρο χαρακτήρα ( π.χ. G) επιστρέφοντας -1.0 Χρησιμοποιήστε την εντολή switchy. Η συνάρτηση θα καλείται όπως στον παρακάτω κδικα. int main() { char grade; cout > grade; cout << "The GPA score is " << grade2number (grade); return 0;
The least common multiple (lcm) of two positive integers u and v is the smallest positive integer that is evenly divisible by both u and v. Thus, the lcm of 15 and 10, written lcm(15, 10), is 30 because 30 is the smallest integer divisible by both 15 and 10. Write a function lcm() that takes two integer arguments and returns their lcm . The lcm() function should calculate the least common multiple by calling the gcd() function from program 7.6 in accordance with the following identity
Write a function in_out (xs, ys, side) which takes three numbers as input, where the side is non-negative. Here xs and ys represent the x and y coordinates of the lower left corner of a square; and side represents the length of the side of the square. (Note that xs, ys and sides completely define a square and its position in the plane). Your function must first prompt the user to enter two numbers that represent the x and y coordinates of a point request. Your function should display True if the given query point is inside of the given square, otherwise it should display False. A point on the limit of a square is considered as being inside the square. No loops, no ifs, no lists To avoid confusion, unless otherwise noted in the questions, here is what you can use in these exercises: - comparison operators: <, <=, ==,! =,>,> = - Boolean operators: and, or, not - arithmetic operators: +, -, *, /, **,%, // - the following Python built-in functions: print, input, round, len,…
The least common multiple (lcm) of two positive integers u and v is the smallest positive integer that is evenly divisible by both u and v. Thus, the lcm of 15 and 10, written lcm(15, 10), is 30 because 30 is the smallest integer divisible by both 15 and 10. Write a function lcm() that takes two integer arguments and returns their lcm . The lcm() function should calculate the least common multiple by calling the gcd() function from program 7.6 in accordance with the following identity: lcm(u, v) = uv / gcd(u, v) u, v >= 0
Write a function that asks the user for their birthday month and day and then the function should call a nested function to find out the person’s zodiac sign. Test your program with some user input. Aries: March 21 - April 19 Taurus: April 20 – May 20 Gemini: May 21- June 21 Cancer: June 22- July 22 Leo: July 23 – August 22 Virgo: August 23 – September 22 Libra: September 23 – October 23 Scorpio: October 24 – November 21  Sagittarius: November 22 – December 21 Capricorn: December 22 – January 19 Aquarius: January 20 – February 18 Pisces: February 19 – March 20
The function doit(a,b,c,d) is a function that multiplies the smallest of its integers arguments by 2. If more than one arguments are equal and are the smallest, they are multiplied by 2. For example given a=5,b=3,c=7,d=9, doit (a,b,c,d) changes b to 6. Write the code of the function doit and test it.
Complete the function quarts_to_liters() that has one parameter as a volume in quarts. The function returns the volume converted to liters, given that 1 quart = 0.946353 liters. Ex: If the input is 69, then the output is: The number of liters is 65.298
Write a function called area_circumference_generator that takes a radius of a circle as a function parameter and calculates its circumference and area. Then returns these two results as a tuple and prints the results using tuple unpacking in the function call accorrding to the given format. [Must use tuple packing & unpacking] !! Example1: Function Call: area_circumference_generator(1) Output: (3.141592653589793, 6.283185307179586) Area of the circle is 3.141592653589793 and circumference is 6.283185307179586
1. Fibonacci series can be created starting from 0 to the desired number. A function can be written for this operation and it can take two parameters: start and end. The default fırst parameter 0 is acceptable. 0, 1, 1, 2, 3, 5, 8, 13, 21, 34, 55, 89, 144, 233, 377, 610, 987, 1597, 2584, 4181, 6765..
Problem 2: Write a function called digitMatch. The function has three integer parameters first , second and third that are positive and have the same number of digits. It returns the number of positions where their digits match. For example, if the function was applied to 17345, 97813 and 17313 it would return 1 because only the 2nd digits match. If parameters have illegal values your function can operate however you choose. For example, a program that uses the function follows. int main() { cout <« digitMatch(168, 567, 767) « endl; // prints 1 cout <« digitMatch(143, 243, 343) « endl; // prints 2 return 0; }
Write and test the “digit” function:Function Prototype: int digit(int n,int k)This function returns the kth digit of the positive integer n. For example, if n is the integer 29,415, then the call digit(n,0) would return the digit 2, and the call digit(n,2) would return the digit 4.
