Ratios Introduction - what are ratios?
Ratios are used to compare different quantities. In this introduction to ratios we will look at what ratios are, how we deal with ratios of different measurement units and that ratios can be simplified. To donate to the tecmath channel:https://paypal.me/tecmath To support tecmath on Pa

Stirling engines and Carnot's engine
Stirling engines and Carnot's engine are rather similar in some respects, especially in that both can be run as heat engines or refrigerators. There is an important difference between them though: Stirling engines can be built, Carnot's engine is an abstraction. This video explains ho

Interesting limit with n factorial. In this video, I use the Pre-Ratio test from analysis in order to calculate a very interesting limit that involves the factorial function. This is a must-see for both calculus and analysis students! At the end, I also provide a quick applied math proof u

Topics in Combinatorics lecture 3.6 --- bounds for factorials and binomial coefficients
Combinatorics is full of estimates, and for many of them one needs bounds on factorials and binomial coefficients. Fortunately, one can often get away with fairly crude bounds that have straightforward proofs. Here I discuss some of these bounds. 0:00 Introduction and brief struggle with
