Solve the given initial-value problem in which the input function g(x) is discontinuous. [Hint: Solve the problem on two intervals, and then find a solution so that y and y' are continuous at x = 𝜋/2.] y'' + 4y = g(x), y(0) = 1, y'(0) = 3, where g(x) = sin(x), 0 ≤ x ≤ 𝜋/20, x > 𝜋/2 y(x) = , 0 ≤ x ≤ 𝜋/2 , x > 𝜋/2

The formula \kappa(x) = \frac{|f''(x)|}{[1 + (f'(x))^2]^{3/2}} expresses the curvature of a twice-differentiable plane curve as a function of x. Find the curvature function of the curve y = -9 cos x, 0 \le x \le 2\pi. Then graph f(x) together with \kappa(x) over the interval. The curvature function is \kappa(x) =

Four strain gauges are connected in a measuring bridge, with two gauges experiencing longitudinal strain $R^+$ and two experiencing transverse strain $R^-$. It applies: $R^+ = R_0(1 + ke)$, $R^- = R_0(1 - ke)$ Calculate the differential voltage $U_D$ as a function of the strain $e$, the k-factor and the input voltage $U_H$

from the point directly beneath you at a constant velocity of 𝑣𝑓=2.50 m/s . You want to calculate the time it takes for the ball to reach your friend. To do this, you can use the following equation: 𝑡=𝑑𝑥/𝑣𝑥 where 𝑡 is the time, 𝑑𝑥 is the horizontal distance, and 𝑣𝑥 is the horizontal velocity. First, let's find the horizontal distance 𝑑𝑥 . We can use the equation: 𝑑𝑥=𝑣0cos(𝜃)𝑡 where 𝑣0 is the initial velocity and 𝜃 is the angle above the horizontal. Substituting the given values, we have: 𝑑𝑥=8.60cos(34.0∘)𝑡 Next, let's find the horizontal velocity 𝑣𝑥 . We can use the equation: 𝑣𝑥=𝑣0cos(𝜃) Substituting the given values, we have: 𝑣𝑥=8.60cos(34.0∘) Now, we can substitute the values of 𝑑𝑥 and 𝑣𝑥 into the equation for time: 𝑡=(8.60cos(34.0∘)𝑡)/(8.60cos(34.0∘)) Simplifying the equation, we have: 𝑡=𝑡 Therefore, the time it takes for the ball to reach your friend is equal to the time it takes for the ball to reach your friend.

QUESTION 6 Sanna and Obadia argued about the definition of $\int_{-\infty}^{\infty} \frac{e^{-x}}{x^2 - 1} dx$ Sanna split the integral as $\int_{-\infty}^{\infty} \frac{e^{-x}}{x^2 - 1} dx = \int_{-\infty}^{0} \frac{e^{-x}}{x^2 - 1} dx + \int_{0}^{\infty} \frac{e^{-x}}{x^2 - 1} dx$ Obadia split it differently as $\int_{-\infty}^{\infty} \frac{e^{-x}}{x^2 - 1} dx = \int_{-\infty}^{-1} \frac{e^{-x}}{x^2 - 1} dx + \int_{-1}^{1} \frac{e^{-x}}{x^2 - 1} dx + \int_{1}^{\infty} \frac{e^{-x}}{x^2 - 1} dx$ Which of the two would you agree with? Clearly explain your choice.
