Cоnsider the well-knоwn trigоnometric identity: (а) (70 points) Write а short MATLAB script to show thаt the function is equal to the function in the time range [-0.25, 0.25] (in seconds) when the angular frequency radians/second. More specifically, construct these two functions , then create a check that is one number, output to the Command Window, that convincingly shows that this identity is true, point by point. Make sure the script is efficient, simplifying expressions and avoiding intermediate variables where possible. In your script, use lower-case "w" to represent the fixed angular frequency . (b) (5 points) Instead of hard-coding the range of values of times used in the check, ask the user to set the initial and final time to evaluate. Your subsequent code in your script should run only if the start time is less than the end time. Execute the script to check the identity over the range of times [-0.25, 0.25] (in seconds). (c) (5 points) The tangent function is well known for having discontinuities at values of that are multiples of . Write code after the input statements that checks if the tangent function will ever be evaluated for inputs below or above , and if so prevents execution of the subsequent code, instead outputting an informative error message. (d) (15 points) Plot these two functions on one figure with one pair of axes; use a continuous line for the first plot and a dashed line for the second, with different colors, so that we can see that the two lines fall on top of one another. Make sure there is a proper legend, a meaningful title, and complete axis labels on your figure. Include the plotted functions in the legend of the figure. Make sure that the legend does not overlap with the plot by leaving enough space for it. Make sure the font sizes are appropriate to the size of the figure. Use at least 1000 samples in time. Create a PDF or PNG file of the figure using the MATLAB interface (using the clipboard, printing, or saving as figure), then append them to the PDF of the command window output. Generating your figures by using screenshots or other methods outside the MATLAB options above will incur a 5 point penalty. (e) (5 points) The tangent function is also well known for being arbitrarily large as gets close to a discontinuity. Add a third input statement asking the user for the largest amplitude of the tangent function that they wish to visualize, and set the range of the plot's vertical axis to go from to . If the user does not enter a positive value for , output a robust and informative error message that includes the value of the user entered. Test your code by setting the time range to [0, 0.49] and setting the largest amplitude to 10.
