Plot the following functions, as described. (a) Truncated power series: f(x)-% +aix + ar, from x =-1 to x 3, with a0-4, a,--3, and a,-2. Make the line dotted and make the line thickness equal to"3pt" (b) Three dampings for parallel RLC: Consider the three voltage functions shown to the right where t is in seconds. Plot all three on one pair of axes, from t 0 tot 40ms. Make them red, green, and blue. Use a legend. (The first is "overdamped", the second is "critically damped", and the third is s, =-800Hz, s,--200Hz, Al-16V, and A,--W; a,-500Hz,A-12V, and B =-6000V/s; and ,-120Hz, -450rad/s, a = 12V, and b =-SV. You will need 2 sheets and 2 charts (in Excel) to do this exercise. On each sheet, set up the dependent variable [x or t) in column A, with the parameters you need above it (e.g, tmin, tmax, N, and dt). Then set up the dependent variables (for v, Va, and v,) in the next column(s), again, with the parameters you need above the appropriate columns of calculated values. You will need at least 400 points in each to make a smooth graph. Move each chart to its own sheet, so that it is easier to edit and print. Use S to suppress the automatic cell referencing, as needed. One point will be taken off for each unnecessary $ Each title should be 32pts, each axis label should be 20pts, and the numbers on each axis shouled be 15pts. The legend for part (b) should be 18pt. (Remove the legend for part (a), if there is one.) For part (a) to make a dotted line, you will need to choose "Smoothed scatterplot. For part (b), note that you will need two columns of time values, one in seconds and the ms. (Think about how to create the second one efficiently.) You will need to compute the values of the functions in seconds, but plot using ms. Also, when pull it out to make the expression you write more efficient other in there is a common factor in each term Submit 6 pages in all: For each part, submit only the first page of and the chart. To m by [any very large number] page(s) tall". Landscape orientation works well for everything especially the formulas and the charts formulas, the first page of values, e the size of the first page, use Further, for part (a), set up your column of x values such that the value of fx) at x- -0.95 is visible on the first page. Similarly, for part (b), set up your column of t values such that the three voltages at t 0.5ms are visible on the first page
