\def\X{\mathbb X} \def\imp{\rightarrow} Defining discrete mathematics is hard because defining mathematics is hard.

3 In other words, induction is a style of argument we use to convince ourselves and others that a mathematical statement is always true. \def\dbland{\bigwedge \!\!\bigwedge}

\def\circleA{(-.5,0) circle (1)} \def\nrml{\triangleleft} This course serves both as an introduction to topics in discrete math and as the "introduction to proofs" course for math majors. \newcommand{\U}{\mathcal U} But let us attempt to prove it. Mathematical induction is a proof technique, not unlike direct proof or proof by contradiction or combinatorial proof. If this is your first time encountering the subject, you will probably find discrete mathematics quite different from other math subjects. \def\circleClabel{(.5,-2) node[right]{$C$}} \(\def\d{\displaystyle} Fundamental set of numbers is the natural numbers.

\newcommand{\pow}{\mathcal P} Left Side = 1 Right Side = 1 (1 + 1) / 2 = 1 Both sides of the statement are equal hence p (1) is true. The master branch here now has the source code for the 3rd edition. What is the range?

Assuming all 10 people at the party each shake hands with every other person (but not themselves, obviously) exactly once, how many handshakes take place?


This thread is archived. In discrete math, we don't have derivatives, so we look at differences. Renowned for her lucid, accessible prose, Epp explains complex, abstract concepts with clarity and precision, helping students develop the ability to think abstractly as they study each topic. CSE 16 Applied Discrete Mathematics Summer 2020 (June 22 – August 14) Description: Introduction to applications of discrete mathematical systems. Discrete math could still ask about the range of a function, but the set would not be an interval.

After excavating for weeks, you finally arrive at the burial chamber. However, there are other topics that belong under the discrete umbrella, including computer science, abstract algebra, number theory, game theory, probability, and geometry (some of these, particularly the last two, have both discrete and non-discrete variants).
