Half integral of x
In my previous post I showed you how to take the half derivative of x. Here, I am going to explain how to find the half integral of x. We… Read more Half integral of x →
Half derivative of x
The derivative of x is easy, it’s simply 1; the second derivative of x is the derivative of 1, which is 0; but what on earth is the half derivative… Read more Half derivative of x →
Einstein’s equation
E=mc². Everybody knows this formula, but not everyone knows what it is, what it means. How can three letters and an exponent mean so much? Let’s start by defining those… Read more Einstein’s equation →
Integral of sec(x)
This integral needs a quite a bit of work but we will eventually be able to evaluate it! Keep in mind that there is a much faster method, but it’s… Read more Integral of sec(x) →
Cauchy principal value | Definite integral of 1/x
We know that the integral of 1/x is the natural logarithm ln(x). Very straightforward, yes, but it’s not as simple when it comes to evaluating the definite integral. As you… Read more Cauchy principal value | Definite integral of 1/x →
