El ydur answers are boxed in; and >> Matlab code, if asked for, is clear and correct. To ease grading and save space, your Matlab code can use shortcut notation like 567 = 18” instead of, say, “theta7dot = 18”. You will be penalized, but not heavily, for minor syntax errors. c) Substantial partial credit if your answer is in terms of well defined variables and you have not substi— tuted in the numerical values.

    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.
