I'm taking my first discrete math course. One aspect of functions has me stumped. We're asked to list the functions from a two-element set to a three-element set. And then list all the functions from ...

Ordinary differential equations (ODEs) and difference equations serve as complementary tools in the mathematical modelling of processes evolving in continuous and discrete time respectively. Together ...

The term orthogonality derives from the study of vectors. Most likely you have run across the term in basic trigonometry or calculus. By definition, two vectors in a plane are orthogonal when they are ...
