3. Consider the function $f: \mathbb{R}^2 - \{(0,0)\} \to \mathbb{R}$ defined by $\qquad f(x,y) = \frac{x^2 - y^2}{x^2 + y^2}$ for all $(x, y) \in \mathbb{R}^2 - \{(0,0)\}$. Use the sequential criterion for limit of function (Proposition 6. 16) to prove that $\lim_{(x,y)\to(0,0)} f(x,y)$ does not exist. 4. Let $f: \mathbb{R} \to \mathbb{R}$ and $g: \mathbb{R} \to \mathbb{R}$ be functions such that $f(x) \neq 3$ for all $x \neq 2$. Use $\epsilon-\delta$ to prove that if $\lim_{x\to 2} f(x) = 3$ and $\lim_{y\to 3} g(y) = 4$, then $\lim_{x\to 2} (g\circ f)(x) = 4$.

This form of aging prevents starvation

Complete the code to output ' t = ' followed by the value of t to three digits after the decimal point. On the same line, output "when s= " followed by the value of s to two digits after the decimal point. End with a newline. Ex: If the input is 1.00 , then the output is: t=-22.000 when s=1.00

(15 marks) The training data is as follows. Each row corresponds to an example. Five examples in total. Integers are used to represent values of attributes. We have three attributes: att1 (with values 0, 1, and 2), att2 (with values 3, 4, and 5), and att3 (with values 6 and 7). The decision variable is with values 'No' and 'Yes'. Training Data att1 att2 att3 decision variable Example A 2 5 7 Yes Example B 1 3 7 No Example C 0 3 6 No Example D 1 5 7 Yes Example E 1 5 6 Yes Use a Naive Bayesian to Classify a new example, which has [2, 5, 6] for the attributes [att1, att2, att3].

1) Write a PowerShell script that takes any command as a parameter and displays help on that command (e.g. the result of execution of get-help <command>). 2) Write a PowerShell script that takes three parameters. If the number of parameters passed to the script is not equal to 3, it prints a warning message and displays a proper usage hint: "Usage: foo.sh param1 param2 param3". If 3 parameters are passed, the script should print some positive message. 3) Write a PowerShell script that takes names of two files as parameters and copies the content of one file into another without asking any questions. The copy should contain a note that it is a copy, the name of the original file, the current date, and time after the content. 4) Write a PowerShell script that takes a file name as a parameter and asks if a user wants to delete that file. If the answer is 'Y' and the file exists, it is deleted. If the file does not exist, an error message is displayed. 5) Write a PowerShell script that asks the user to enter a positive integer number, prints that number, and prints whether that number is odd or even. 6) Write a PowerShell script that takes a file name that does not currently exist as a parameter and asks if a user wants to create that file. If the answer is 'Y' and the file does not exist, it is created. If the file does exist, an error message is displayed. 7) Write a PowerShell script that asks the user's year of birth and prints "Minor" if the user is younger than 21, "Senior" if the user is older than 65, "Workforce" otherwise. 8) Write a PowerShell script that plays the guess-a-number game, shrinks the range with each guess, and counts attempts. Your program should correctly process a case when a user enters a number smaller than the current min or greater than the current max. In such cases, an attempt counter should change, but the range must stay the same. 9) Write a PowerShell script that takes a directory name and a file extension as parameters, creates a directory with the specified name, and moves all files with the specified extension from the current directory to the new one. 10) Write a PowerShell script that takes a number and a character ('C' or 'F') as parameters and converts that number from Celsius to Fahrenheit (if 'C' is passed) or vice versa (if 'F' is passed). If the number of parameters passed is not equal to 2, your script displays a usage note: "temp.sh <Temperature> <C|F>".
