The Natural Numbers and Zero (Types of Numbers #2)

I now begin the escapade into different sorts of numbers. This may seem rather a strange adventure to anyone who hasn’t listened to too many professional mathematicians talks, or anyone who is too far removed from high school education. I would guess that most people who have read this have some particular picture of numberContinue reading “The Natural Numbers and Zero (Types of Numbers #2)”

Riemann Sums and Areas (Explaining Calculus #14)

At this point in calculus, we are taking what appears to be a sharp turn in a direction completely away from what we’ve been doing so far. We now turn to talking about areas. The Problem Geometry is one of the most important branches of all mathematics, both theoretical mathematics and applied mathematics. When middleContinue reading “Riemann Sums and Areas (Explaining Calculus #14)”

Why Ask Questions About Numbers? (Types of Numbers #1)

This is a first post in a series in which I’d like to discuss various different types of numbers that mathematicians study. This may sound strange – and that is fair. After all, aren’t all numbers just… numbers? Why would some numbers be so different from other numbers? What sense does that make? I’m honestlyContinue reading “Why Ask Questions About Numbers? (Types of Numbers #1)”

The Importance of Derivatives and What Comes Next (Explaining Calculus #13)

This post doesn’t exactly introduce anything new about calculus. But, we must remember, it is important to reflect whenever we learn. Even in mathematics. In this post, I plan on achieving two main goals. One, we will reflect on what we’ve done so far by introducing the new ideas of limits and derivatives to ourContinue reading “The Importance of Derivatives and What Comes Next (Explaining Calculus #13)”

Higher Order Derivatives and Their Applications (Explaining Calculus #12)

Up to this point, I’ve focused my efforts on derivatives of functions and what those derivatives mean. In particular, derivatives tell us about how things change over time – with derivatives, we can measure quantities like speed and growth. But derivatives are also functions, which means they have their own derivatives. Can we learn anythingContinue reading “Higher Order Derivatives and Their Applications (Explaining Calculus #12)”

Exponential Models (Explaining Calculus #11)

We’ve used calculus for a couple different applications at this point. I’d like to tack on another application to our list, perhaps the most important one – at least from the perspective of a society very reliant on technology, engineering, and science. The application I have in mind goes under the very broad title ofContinue reading “Exponential Models (Explaining Calculus #11)”

Optimizing Real-World Stuff (Explaining Calculus #10)

In the previous post in this series, I explained how you can use derivatives to locate maximizing and minimizing values for functions. Now, I will put that knowledge to use in concrete examples to show exactly how this works. Example 1: Building a Fence Imagine the following situation. You are a farmer, and you wantContinue reading “Optimizing Real-World Stuff (Explaining Calculus #10)”

Locating Peaks and Valleys with Derivatives (Explaining Calculus #9)

We have gone through a couple of discussions now on how to actually calculate the value of a derivative. This is great, after all what good is a shiny new tool if you don’t know how to operate it? But we are done with that now. Now that we’ve gone through a tutorial with derivatives,Continue reading “Locating Peaks and Valleys with Derivatives (Explaining Calculus #9)”

Computing Derivatives: Part 2 (Explaining Calculus #8)

Most recently in the series on calculus, we did some overview on some “precalculus” topics that we’d need for later calculus discussions. Having now done this, we move on to several examples of more ‘complicated’ rules that derivatives follow. We will then investigate some more difficult specific functions and their derivatives. Finally, at the end,Continue reading “Computing Derivatives: Part 2 (Explaining Calculus #8)”

Topics From “Precalculus”: Part 2 (Explaining Calculus #7)

Because of the directions I’d like to be able to go later on in this series, we need to make an aside about more topics that aren’t specifically calculus related. If you’ve made it this far, great for you! You’re now getting into the realm of calculus. This is a fun ride, and it isContinue reading “Topics From “Precalculus”: Part 2 (Explaining Calculus #7)”
