MatLab Homework: I have no idea how to solve thses problem. would you please provide the code for me to copy it

Write your solutions within a single script file. Hardcopy: submit your e figure windows and workspace. Upload you .m file on ecampus. ditor, command, 1. Write a program to calculate the sum of the first n terms of the series (-1)*x2k+1 (2k 1)! Your program must use for-end loops and must also Execute your script file for n-10 and x-195. implement an fprintf command to display the final answer 2. The position as a function of time (x.y) of a projectile fired with a speed vo at an angle by a is given X-Vocos(a)*t y-vsin(a) *t-0. 5gt2 where g is the gravitational acceleration (9.8m/s?). Use while-end loop to calculate the trajectory (x,y) of a projectile fired at a speed v,-10m/s and an initial angle ? of 45. Your program must stop once the projectile reaches the ground. Use the values of x,y to plot the trajectory of the projectile Given vector Z-[1 45 13 2 34 11 45 21 24 6 1873 1121 2 3 56 15 10 25 1 5 2 22 9], write a script file that will determine the number of elements in vector Z with value greater than than 20. Your program must use loops and must display the final answer using a command 3. 0 and less n fprintf
