including code please

Problem 3 (Matlab) (a)Using Matlab, plot the sin and cos functions from to a using 101 equally-spaced points, with the sin curve plotted with a dashed line. Label the x-axis as "y" and y-axis as "function values", title the plot as "My Plot, and use the legend command to distinguish the two curves. Please include the Matlab script. Hint: The x-values can be derived using the colon operator, i.e., =-1: 21 100 :. (b) Write the loop(s) for computing the value of 1+3+5+7+ + 101 1 *3*5*7*... * 101
