Lec 2 MIT 18.085 Computational Science and Engineering I
two and the topics are applications in one dimension uh and uh this is what's new this is the key part that's new here so now we're dealing with the question of finding the matrices finding the equations where do they come from and this is the going to be the key to that so again we we will end up with one of these symmetric products an A and an a transpose it happens that the a goes on the right and the a transpose on the left but the point is one is the transpose of the other and uh the product is of course square and symmetric okay but now where what's the application and these are going to be uh the matrices that come up uh if I create the right application and the discussion in the text is in section 1.4 I there're going to be examples with masses and springs because that's the most basic problem of mechanics so I know that your interests go all over the field of Applied Mathematics and uh lots of it so mechanics uh are sort of the natural top...
