16. Use a for-end loop in a scrip file to calculate the sum of the first n terms of the series y- Show how to execute the script file for n-s. 17. Use the flot command to plot the function fxi in the domain7sxs7 with interval 0.01 18. A parametric equation is given by Plot the function for from -2 to 2 sts . Form at the plot such that the both axes will range Add a legend and label the axes. 19. A vector is given by M-[s 17 -3 8 -7 12 15 20 1 -6 -3 4 -7 16] Write a program as a script file that doubles the elements that are positive and are divisible by 3 or 5, and, raises to the power of 7 the elements that are negative but greater than -5 20. A model for exponential growth or decay of a quantity is given by At Aoe where A (t) and Ao are the quantity at time t and time 0, respectively and k is a constant unique to the specific application. Write a user-defined function that uses this model to predict the quantity A(t) at time t from knowledge of A0 and A(t1) at some other time tl. For function name and arguments, use At -expGD (A, At 1, t1, t). where the output argument At corresponds to A(t), and for input arguments, use Ao, Atl, ti, t t corresponding to A0, A(tl), t and t, respectively
