Applied Math Problems – Real World Math Examples

Applied Math Problems – Real World Math Examples will cover many real life uses of Math from Algebra to advanced Calculus and Differential Equations.

Please keep in mind, the purpose of this article and most of the applied math problems is not to directly teach you Math.

If you use this as a reference please be sure to properly cite us and link to the original. Thank you 🙂

Why is Kinvert Making Applied Math Examples?

Though I have a Mechanical Engineering Degree and an Aerospace Engineering Degree, I wasn’t always good at Math.

As with most things in my life, I struggle with things I don’t see the point of.

Sure, I could find that x + 5 = 10, sure, x = 5. Who cares?

But when I was trying to solve a real world problem I independently invented Newton’s Method, Numerical Integration, etc.

I learn when I know the WHY of what I’m learning.

That’s what this article on applied Math examples is all about. I’m not here to directly teach you Math, at least in these articles. This all exists to help show you the reason and uses for Math in the real world.

If you know a real world use of a Math concept, please let me know in the comments below!

We Will Be Updating These Applied Math Problems and Real World Math Examples

Applied math examples real world math problems kid confused by large equation

This is a living list that will be updated with time. Some of these topics might end up with so many example’s we’ll have to link to a separate article for it. For example, if we list every example where we use a Function, which is a topic of Algebra, that list in and of itself would contain just about every real world math example we’ll make.

We divided these applied math problems and real world math examples in to mathematical disciplines.

Applied Algebra Examples

Applied Differential Equations Examples

Application of Differential Equations to calculate heat transfer through a brake rotor Applied Math Kinvert

In college I struggled with Differential Equations at first because the only use I really saw was certain circuits and harmonic motion.

So I set out to find a use, and I ended up simulating the heat transfer through brake rotors. I personally learn Math best when I see actual uses. Let’s look at real life uses of Differential Equations.
