Proof Without Words: If x >0, x + 1/x >=2

A picture is worth a thousand words, even in mathematics. Most of the time, complicated algebraic statements can be shown using geometric representations. One example is the sum of which when added equals 1. In this post, we show another geometric proof without words. Proof without words is not a proof per se but rather […]

A Fascinating Introductory Video to Mathematical Proofs

I recently came a cross with a great introductory video about mathematical proofs titled How to Prove a Mathematical Theory. The video  which was produced by TED explains what is a mathematical proof, discusses a very brief history, and illustrates with an example. I hope you enjoy it as much as I did.

11 Proven Proof Techniques Non-Math Majors Should Know

Proofs is the heart of mathematics.  It is what differentiates mathematics from other sciences.  In mathematical proofs, we can show that a statement is true for all possible cases without showing all the cases. We can be certain that the sum of two even numbers is  even without adding all the possible pairs.     […]
