Written Lab Task \#3 Due Date: Friday, December 6 at 11:59 PM Mountain Time Upload your solution to Gradescope [Video on how to submit]
Question: The following is a transcription of a real conversation with ChatGPT (the artificial intelligence language model that has been in the news lately) that Jerrod had on January 25, 2023.
User input: "How do you integrate $f(x) g(x)$ ?" ChatGPT: "To integrate $f(x) g(x)$ , use the product rule of integration. The product rule states that: $\int f(x) g(x) d x=\left(\int f(x) d x\right) \cdot\left(\int g(x) d x\right)+C$ where $C$ is the constant of integration. It's important to note that this formula only holds if both $f(x)$ and $g(x)$ can be integrated individually. If that's not the case, you may have to use other integration techniques." (a) Two real-valued functions $F(x)$ and $G(x)$ are not equal if either they have different domains, or if they have the same domain and there is a number $x=a$ so that $F(a) \neq G(a)$ . Show that $F(x)=\frac{1}{x}$ is not equal to $G(x)=\ln |x|$ . Note that $F$ and $G$ have the same domain. (b) Choose non-constant functions $f(x)$ and $g(x)$ and use them to demonstrate that ChatGPT is incorrect. Do this by computing the righthand side of the above equation to obtain a function $h(x)$ and then showing that $h(x)$ is not an antiderivative of the product function $f(x) g(x)$ . That is, show that $h^{\prime}(x)$ is not equal to $f(x) g(x)$ . (c) For the functions $f(x)$ and $g(x)$ that you chose in part (b). Compute $\int f(x) g(x) d x$ correctly. (Optional Challenge) Claudia chose $g(x)=\cos (x)$ . You get to choose any non-constant function $f(x)$ . Now compute $\int f(x) g(x) d x$ correctly. Reminder: Explain your answers using good notation, organized calculations, and a few full sentences. (C)University of Calgary

Reason Abstractly During a test flight, Jeri's rocket reached a height of 18 yards above the ground. This was 7 yards less than the height that Devon's rocket reached. Did Devon's rocket reach a height greater than 23 yards? Explain. Choose the best answer and explanation. A) no; If I solve the equation $x-7=18$ to find the height that Devon's rocket reached, I find that Devon's rocket reached a height of $18-7$ , or 11 yards. Because $11<23$ , Devon's rocket did not reach a height greater than 23 yards. B) no; If I solve the equation $x+7=18$ to find the height that Devon's rocket reached, I find that Devon's rocket reached a height of $18-7$ , or 11 yards. Because $11<23$ , Devon's rocket did reach a height greater than 23 yards. C) yes; If I solve the equation $x-7=18$ to find the height that Devon's rocket reached, I find that Devon's rocket reached a height of $18+7$ , or 25 yards. Since $25>23$ , Devon's rocket did reach a height greater than 23 yards. D) yes; If I solve the equation $x+7=18$ to find the height that Devon's rocket reached, Ifind that Devon's rocket reached a height of $18+7$ , or 25 yards. Because $25>23$ , Devon's rocket did reach a height greater than 23 yards.

In Figure 2, the person uses a double pulley. The person pulls down on the rope at the same constant speed. The bell again moves upward at a constant speed, but the speed of the bell is half the speed of the bell in Figure 1 . The power delivered to the bell in Figure 2 is $P_{2}$ . Which of the following correctly compares $P_{2}$ to $P_{1}$ and provides a valid justification? (A) $P_{2}<P_{1}$ , because in Figure 2 the force exerted on the bell is the same but it is moving with less speed than in Figure 1. (B) $P_{2}<P_{1}$ , because in Figure 2 the force exerted on the bell is less than in Figure 1. (C) $P_{2}=P_{1}$ , because in Figure 2 the speed is half that in Figure 1 , but the force on the bell is twice that in Figure 1. (D) $P_{2}=P_{1}$ , because in Figure 2 the person is doing the same amount of work on the bell as in Figure 1.
