MAE107 Course Goals “To develop efficient , computer-based solutions to engineering problems Engineering problems - usually stated in mathematical terms derived from the conservation laws
Goal: “Computer - based” Computers allow for application to large, complex systems and help us avoid tedious calculations. Computer programs provide a set of tools for tackling similar problems Goal: “Efficient” Use the appropriate numerical method to get fast, accurate solutions to stated problems

### What students are saying

• 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.
