I need help on this MATLAB problem, please help!

  1. PROBLEM STATEMENT: PART ONE
  2. 1. Consider the signal [n] = 4cos(n) + 6sin(n). Represent, but do not print out, this signal using a list of time values and a list of signal values from n = -240 to n = 240. Call the list of time values "n" and the list of signal values "x".
  3. 2. Determine and print out the time value(s) where the maximum value of this signal occurs. Let "xmin" denote the minimum value of this signal and let "nmin" be the time value(s) where this minimum occurs. Use MATLAB to determine and print out these values, including the names of the variables.
  4. 3. Let "nzero" denote the time values where [n] is closest to zero. Use MATLAB to determine and print out these time values, including the name of the variable. Hint: [n] is closest to zero at the time values where x[n] is minimum.

What should be the distance between the object in Exercise 9.24 and the magnifying glass if the virtual image of each square in the figure is to have an area of 6.25 . Would you be able to see the squares distinctly with your eyes very close to the magnifier? [Note: Exercises 9.23 to 9.25 will help you clearly understand the difference between magnification in absolute size and the angular magnification (or magnifying power) of an instrument.]

Can someone help me? A use of rows is to obtain an approximate value for a (convergent) row by calculating the final sum aj i = no ou =! One difficulty with this method is knowing how large n must be to obtain sufficient accuracy. This is often given as how many current digits, or how many decimal places we need. A practical way to do this is to see which decimals do not change if we increase n (a lot), for example, it doubles. The method is not safe and can potentially give completely wrong answers, but in practice, it almost always works. Practitioners (engineers and physicists) like this method, while mathematicians are often a little more skeptical. In this thesis, I will suppress my skepticism and ask you to use this method to find the sum of the row + 25/+3 with 4 decimal places accuracy. i = 23 - 20i + 2 - 3. This should be done by starting with the upper limit n = 2 = 2 then double the number of joints repeatedly until the difference between the last two estimates is less than 10 = 0.001. What is the smallest number k so that the difference 25i + 3 25i + 3 60 3 23 - 201 + 2 /= 2 3 - 201 + 2? Some hints: One way to calculate a sum is by def sum(n0, n): 0 = uawwns for i in range(n0, n + 1): summen = summen + a(i) return summen - 3 is less than 10? a i is a function expression for the i-th clause, and must, of course, be adjusted according to the thesis text: It is best if you manage to automate the search with a while loop that stops when the difference is small enough, but a partially manual variant also works (but you have to count on some repetitions).

Problem 2: Three people push on a box from different sides and with varying strengths. (See Fig. 2) Determine the resulting acceleration of the box. Comments: An illustration of the contrived system is provided in Fig. 2. The mass of the box is m = 10 kg. The magnitude and direction of each force are specified in the figure. You can use Newton's Second Law F = ma to determine the acceleration. Recall that we may equate the x-component of the left-hand side of this equation to the x-component of the right-hand side. We may do the same for the y-components. Mass of box = 10 kg F2 = 6 N F = -(8 N) axis axis = 10 N FIG. 2: Sketch of the system described in Problem 2. A box of mass m = 10 kg is pushed by three forces. You are asked to determine the acceleration of the box.

5. 15 points) A long string of wire is tightly coiled snakewise so that it forms a flat disk in the xy plane, containing a very large uniform number N of turns per unit distance along its radius. The coil is centered at the origin, such that the inner radius is a and the outer radius is b, and the wire is made to carry a current I going in the counterclockwise direction. a) Find the direction of the B field in the region r < a, where r^2 = x^2 + y^2, in the xy plane. b) Find the magnitude of the B field at the origin. c) Let C be a closed circular circuit of radius a/2 centered on the origin. Evaluate the integral ∮ B · dl directly, and discuss how your result agrees or disagrees with Ampere's law.
