Introduction In this project, we will ultimately be refreshing our previous knowledge of MATLAB functions, coding styles, and processes. By going through a few introductory problems, we are able to fall back into our routine of coding in MATLAB and we are able to pick up on processes previously learned in our past classes. The main problem we will be working today is a simple function plotted using specific time constraints as follows: Plots a) x(t) = 6e −3t sin(2π8t) b) z(t) = 4e −10t cos(2π40t)

    As a current student on this bumpy collegiate pathway, I stumbled upon Course Hero, where I can find study resources for nearly all my courses, get online help from tutors 24/7, and even share my old projects, papers, and lecture notes with other students.

    I cannot even describe how much Course Hero helped me this summer. It’s truly become something I can always rely on and help me. In the end, I was not only able to survive summer classes, but I was able to thrive thanks to Course Hero.

    The ability to access any university’s resources through Course Hero proved invaluable in my case. I was behind on Tulane coursework and actually used UCLA’s materials to help me move forward and get everything together on time.
