Assignment
Write your programs using Racket functional language.
Run each of the programs as many times as necessary to show that different situations are handled properly.
i. In the beginning of each part of this problem, introduce a named value pi, which is 3.1416. You will have to write a function my_calc that takes two numerical parameters. If the first parameter is 1, calculate the area of a circle, whose radius equals the second parameter of the function. If the first parameter is 2, calculate the volume of the sphere, whose radius equals the second parameter of the function. For other values of the first parameter and for a non-positive second parameter return a false Boolean value.
o Implement a function my_calc using a multiple-way selection structure when checking the value of the first parameter.
o Implement a function my_calc using a two-way selection structure when checking the value of the first parameter.
ii. Write a Racket function rem_second that takes a simple list as a parameter and returns a list identical to the parameter except with the second top-level element removed. If the given list does not have two elements, the function should return an empty list.
iii. Write a Racket function my_union that returns a union of two simple list parameters that represent sets. Remember that duplicate elements are not allowed in a set. You are only allowed to use a program ‘membership.rkt' from the folder ‘DrRacket' under ‘Modules'; no other functions!
iv. Write a function my_delete that takes two parameters: an atom and a list (which may be a nested list). This function will produce a list, identical to its parameter list, except with all occurrences of an atom parameter removed, no matter how deep they were. The produced list should not have anything in place of the deleted atoms.
Format your assignment according to the following formatting requirements:
i) The answer should be typed, using Times New Roman font (size 12), double spaced, with one-inch margins on all sides.
ii) The response also includes a cover page containing the title of the assignment, the student's name, the course title, and the date. The cover page is not included in the required page length.
iii) Also include a reference page. The Citations and references must follow APA format. The reference page is not included in the required page length.
