Quantifiers – but they weren’t really there…
Alright, but who needs this? In most mathematical definitions and theorems, concepts like “every” and “exists” are used. See how to use them correctly.
If you’ve been studying mathematics at university for a while now, you’ve probably noticed that most of the material covered in high school doesn’t directly help you at university. If you’re just starting out – take note of this.
Let’s get to work. In this and the next posts, I’ll show you a few details, understanding which will greatly ease your university studies. We start with… The geometric interpretation of absolute value (as distance).
This post is dedicated to a piece of a high school exam question sent to me by a high school graduate via email. It’s worth taking a look out of curiosity and never repeating again that university math is harder than advanced high school math.
Here I show the derivation of the height formula in a right-angled triangle.
When it comes to using many mathematical tools (such as online calculators), we face a not-so-small problem, which is how to write something like this, for example {e^x}/{e^x^2+1}
… “so that the computer understands”. In other words, learning to type mathematical formulas and equations using a computer keyboard. This is neither easy nor pleasant. Don’t expect quick successes, but rather prepare for a hefty dose of frustration, especially when starting with more complex expressions.
I get a lot of questions about the formula for the canonical form of a quadratic function introduced in my Course on Indefinite Integrals. Why is there a^2? Let me explain.
