- Pb#1: For several values of x, confirm that eix = cos x + i sin x Pb#2: An object thrown vertically with a speed vo reaches a height h at time t, where h= vo*t - gt2 Write and test a function that computes the time t required to reach a specified height h, for a given value of vo. The function's inputs should be h, vo, and g. Test your function for the case where h=100 m, vo=50 m/s. and g=9.81 m/s2. Interpret both answers. (MATLAB)arrow_forwardPython question please include all steps and screenshot of code. Also please provide a docstring, and comments throughout the code, and test the given examples below. Thanks. Implement function heads() that takes no input and simulates a sequence of coin flips.The simulation should continue as long as 'HEAD' is flipped. When the outcome of a flipis 'TAIL', the function should return the number of 'HEAD' flips made up to that point.For example, if the simulation results in outcomes 'HEAD', 'HEAD', 'HEAD', 'TAIL', thefunction should return 3. NOTE: Recall that random.choice(['HEAD', 'TAIL']) returns'HEAD' or 'TAIL' with equal probability.>>> heads()0 # TAIL is the outcome of the first coin flip>>> heads()2 # The coin flips were HEAD, HEAD, TAIL>>> heads()1 # The coin flips were HEAD, TAIL>>> heads()5 # The coin flips were HEAD, HEAD, HEAD, HEAD, HEAD, TAILarrow_forwardlllustrating your answer using the buggy code below, explain in your own words what it means for variables to be defined “as locally as possible”, and why it is important. This code is intended to print one of two messages depending on whether an integer input is less than a secret number or not. The function, inputInt, correctly prints the given String and then returns a number input by the user.arrow_forward
- Write a function called monkey_experiment that takes in a goal string (e.g., "methinks it is like a weasel") and a number of iterations as an argument. Run the experiment for that many iterations, and return a tuple with the highest-scoring text that was generated along with the score that it got. Test results: >>> monkey_experiment("methinks it is like a weasel",100000) ('m ojindoebjrerloiuc m oaanvl', 8) >>> monkey_experiment("methinks it is like a weasel",100) ('yeanpqj twosisjcvqrrfu eagbi', 5) >>> monkey_experiment("brevity is the soul of wit",100000) ('nnebptorcrytbe wogl uygdsn', 8) >>> monkey_experiment("to be",100000) ('tofbe', 4) >>> monkey_experiment("to be",200000) ('tbhbe', 3) >>> monkey_experiment("to be",500000) ('eo be', 4)arrow_forwardPlease help using javaarrow_forwardDefine an enumeration type, triangleType, that has the values scalene, isosceles, equilateraland noTriangle. Write a function triangleShape that takes as parameters three numbers, each of which represents the length of a side of the triangle. The function should return the shape of the triangle. (Note, ina triangle, the sum of the lengths of any two sides is greater than the length of the third side). Write a program that prompts the user to input the length of the sides of a triangle and outputs the shape of the triangle. The user can enter the sides in no particular order. C++arrow_forward
- Define function print_popcorn_time() with parameter bag_ounces. If bag_ounces is less than 3, print "Too small". If greater than 10, print "Too large". Otherwise, compute and print 6 * bag_ounces followed by "seconds". End with a newline. Remember that print() automatically adds a newline. Sample output with input: 7 42 secondsarrow_forwardcomplete the fruitful function below. The string parameter, aString, is in the form "age last,first", where last and first are separated by a comma, and age and last are separated by one or more space. The function should return a string containing first and last, separated by exactly one space. For example, if aString has the value 22, Swift, Taylor', then the function would return the string 'Taylor Swift'. def get_first_last (aString): Python Programmingarrow_forwardDraw a flowchart for the Frazzle function.arrow_forward
- Fix an error and show it please? And here are the information about the homework and for the error too. def kwargs_to_args_decorator(*args, **kwargs): This question is meant to test your knowledge of creating a decorator that accepts an arbitrary number of positional and keyword arguments, to decorate a function that accepts an arbitrary number of positional and keyword arguments, and alters the arguments before passing them to the decorated function. When the decorated function is invoked, this decorator should modify the arguments the decorated function receives. This decorator should filter out all positional arguments passed to the decorated function, which are found in the positional arguments passed to the decorator when the decorator was initialized. It should also filter out all keyword arguments with keys that are found in the keyword arguments given to the decorator when the decorator was initialized. After performing the modifications to the arguments, the decorator should…arrow_forwardJavascript I am stuck on a piece of code and I can quite figure out how to finish one part of this function. This is what I have so far: const usersTestArray = [ {id: "1", name: "Joe Graham", option: "option1"}, {id: "2", name: "Kyle Howell", option: "option2"}, {id:"3", name: "Lucy Bauch", option: "option3"}, {id: "4", name: "Sammie Lebsack", option: "option4"} ] const createSelectOptions = (usersTestArray) => { if(!usersTestArray){ return undefined } return userTestArray.map((x) => x.option) } Most of this is correct, however, in the function above, I need to add a create an option element for each user in the array with document.createElement(). I then need to assign the user.id to option.value and the user.name to option.textContent. then it is supposed to return an array of option elements.arrow_forwardIn this version of the game, the length of the snake doubles each time it eats food (e.g. if the length is 4, after eating it becomes 8). Create a function that takes the side n of the game screen and returns the number of times the snake can eat before it runs out of space in the game screen.
