Please do in MATLAB,

For this homework assignment, your solution to each problem will produce a figure. It is essential that the figures not "overwrite" each other when you publish your script m-file. You can make sure this doesn't happen by assigning a unique figure number in each section of your code, with one figure per section (problem). For example, in the first section (for Problem 1), you will have figure (1). In second section (for Problem 2), you will have figure (2) 1. Create a figure that has two curves. Both curves will be on a common set of axes. The two curves are: y = sin(2 The first curve should have a solid black line, and the second curve should have a dashed blue Iine You are free to choose the sample period. If you choose a sufficiently small sample period, the two curves will look correct. If your curves don't look like a sine-wave and a cosine-wave, consider the possibility that your sample period is too large The horizontal axis should run from 0 to 4, and the vertical axis from-1 to 1. On the vertical axis, the tick marks (and tick labels) should be located only at -1, 0, and 1 Use a font size of 18. Use a line width of 2 points for all lines Apply suitable x-axis and y-axis labels and a suitable figure title 2. Create a stem plot of a sampled sine-wave. You should plot at least one cycle. The phase advance per sample (w) should be =2 /16 On the vertical axis, the tick marks (and tick labels) should be located only at -1,0, and Use a font size of 18. Use a line width of 2 points for all lines Apply suitable x-axis and y-axis labels and a suitable figure title
