Engineers usually measure angles in degrees, yet most computer programs and many calculators require that the input to trigonometric functions be in radians. i. Write and test a function call DegToRadFunc that changes degrees to radians and Write another function RadToDegFunc that changes radians to degrees. Write another function called DegRadFunc that does the work of both DegToRadFunc and RadToDegFunc. Your functions should be able to accept both scalar an matrix input. ii. ... 11.

As computer costs declined, it becomes feasible for every student, regardless of economic circumstance, to have a computer and use it in school. This creates exciting possibilities for improving the educational experience of all the students worldwide. The use of computers in education is referred to as computer assisted instruction. Module 1: WAP to help the school student to learn mathematical operations. Use the rand function to produce two Positive one digit integers. The program should then prompt the user with such a question as “how much is 6 * 7?” “how much is 5+4?” The student then input the answer. Next the program checks the answer. If it's correct display the message “very good” and ask another question if the answer is wrong display the message “no please try again” Module 2: one problem in CAI environment is student fatigue this can be reduced by varying the computer's response to hold the student’s attention. Modify the program so that various comments are…
Write a function that takes a gross salary and calculates the net salary by deducting: • 7.65% for FICA • x for federal taxes • y for state taxes • z for local taxes Also, deduct $75 for parking fees and $22.50 for a gym membership. The federal tax rate must be between 10 and 37 percent. The state tax rate must be between 3.25 and 11.33 percent. The local tax rate may not be greater than 3%. If any of those values are outside the valid range, return INVALID_PERCENTAGE from your function. Federal, state, local taxes, and gym membership amounts should be passed in by value. FICA and parking should be a global constant. COMPUTER LANGUAGE IN C
Write a function that takes the current date and corrects the number of days, if it's wrong. The function must return true if the date passed to it is a valid date and false, if not. The main function uses the returned value to either print "Date validated", if a valid date was entered or "Invalid date entered. Changed to ", followed by the modified date.
An integer is said to be prime if it’s greater than 1 and divisible only by 1 and itself. For example, 2, 3, 5 and 7 are prime, but 4, 6, 8 and 9 are not. a) Write a function that determines whether a number is prime. b) Use this function in a script that determines and prints all the prime numbers between 1 and 10,000. How many of these 10,000 numbers do you really have to test before being sure that you have found all the primes? Display the results in a <textarea>. c) Initially, you might think that n/2 is the upper limit for which you must test to see whether a number is prime, but you need go only as high as the square root of n. Why? Rewrite the program using the Math.sqrt method to calculate the square root, and run it both ways. Estimate the performance improvement.

# Write a function called ex3(n) which# 1. accepts as an input parameter an integer between 1 and 100# 2. Calculates and print the mersenne primes between 1 and this number# See en.wikipedia.org/wiki/Mersenne_prime for details# 3. Invoke ex3(16) to print results
The Function will be able to calculate the area of the following polygons: Right triangles, Rectangles, and regular polygons. It will do so by taking the following inputs: - numSides – a double of the number of sides the polygon has - sideLengths – a double of the length or lengths of sides of the polygon The program should determine if the inputs are formatted properly. The rules are: - numSides must be a positive integer number with values greater than or equal to 3. - When numSides is 3 or 4, sideLengths can either be a scalar or an array with two values. - When numSides is greater than 4, sideLengths must be a scalar. To determine if a number is an integer, you can use the rem function. rem returns the remainder of whole number division. It has the following syntax: remainder = rem(numerator, denominator); Where remainder is the remainder of numerator/denominator. To use this to find whether a number is an integer, use rem in the following way: remainder = rem(number, 1); When…
One lap around a standard high-school running track is exactly 0.25 miles. Define a function named laps_to_miles that takes a number of laps as a parameter, and returns the number of miles. Then, write a main program that takes a number of laps as an input, calls function laps_to_miles() to calculate the number of miles, and outputs the number of miles. Output each floating-point value with two digits after the decimal point, which can be achieved as follows: print (f' {your_value:.2f}') Ex: If the input is: 7.6 the output is: 1.90 Ex: If the input is: 2.2 the output is: 0.55 The program must define and call the following function: def laps_to_miles (user_laps) 461710.3116374.qx3zqy7 LAB ACTIVITY 1 # Define your function here 21 3 00 Jo UAWN P 4 if ___name__ 5 6 7.8.1: LAB: Track laps to miles 7 8 main.py '__main__': # Type your code here.

Write a section of Python code (not an entire function) that: Asks the user to input a number between 1 and 10.You do not need to validate the user's input. Displays the message, "This is a low number." if the number is from 1 to 5. Displays the message, "This is a high number." if the number is from 6 to 10. Write the Python code as efficiently as possible.
Q1. Write a program so that it asks for x and n values to calculates the sum of the following series and print the result from the main function; the x value should be float and n is integer. Note: Create two functions, Power (int, float) and Factorial (int), the main function will pass arguments to both functions and receive the retune values. x7 x" SUM = 1 + + 3! 5! (n-1)! 2!
