In what case do you use ./ or .* to multiply two arrays vs / and * alone? I'm confused about these two questions below, can someone answer the two questions below and explain?

Perhaps start with doing a little bit of reading in the documentation:
Array vs. Matrix Operations
This is a fundamental concept in MATLAB, and there are lots of related pages in the DOC.
Good luck!

\ this is mldivide. solves the system of linear equations A*x = B.
/ this is mrdivide. perform right-matrix division, which is same as A*inv(B)
./ this is element by element division.
/. or ./. there are no such operators in MATLAB.
