Use the fourth-order Runge-Kutta subroutine with h = 0.4 to approximate the solution to the following initial value problem at x = 0, 0.4, 0.8, ..., 12. Use your answers to make a rough sketch of the solution on [0,12]. Note whether or not $\frac{\partial f}{\partial y}$ is bounded. y'= cos (8y) + 2x, y(0) = 3 Let y' = f(x,y). Find $\frac{\partial f}{\partial y}$ and determine whether or not it is bounded on the vertical strip S = {(x,y): 0<x<12, $-\infty$ <y<$\infty$}. Select the correct choice below and fill in the answer box to complete your choice. A. $\frac{\partial f}{\partial y}$(x,y) = is bounded. B. $\frac{\partial f}{\partial y}$(x,y) = is not bounded.

Write a program that asks the user to input a series of numbers. When the user enters zero, the program must stop accepting numbers. The program must then report to the user the highest number entered. An example of the program's output is as follows: Enter a number (0 to quit): 31 Enter a number (0 to quit): 53 Enter a number (0 to quit): 42 Enter a number (0 to quit): 23 Enter a number (0 to quit): 0 The highest number was 53.

a) For the circuit in Figure 4, find s-domain expression for the voltage $V_C$ across the capacitor C=25mF, and the voltage across the inductor, $V_L$. Assume initial conditions of $i(0^-) = 3A$ and $V_C(0^-) = 0$. b) Find the time-domain expressions of $V_C$ and $V_L$. [Hint: take the inverse L- transforms of the expressions that you found before]
