17. ### Linear Ordinary Differential Equation with Constant Coefficients

Linear Ordinary Differential Equation with Constant Coefficients. This is a concise outline and summary of a solution paradigm for the topic, ie, just follow the steps, and do and interpret the resulting algebra. L(y) = a_{0}y^{(n)}+...+a_{n-1}y'+a_{n}y = 0 By substitution, e^{rx} is a...
18. ### Twin Prime counting function & Euler constant

Hi everyone! I am new to the forum. In my spare time, I've been trying to find a way to count twin primes under any given x. I know there is a method that exists that utilizes the Twin Prime Constant. Anyways, I found the distribution of twin primes to be related to the Euler-Mascheroni...

20. ### Mimicking RC time constant

I have a signal which is sampled every 0.2 seconds and decided I wanted to apply a simple filter to the data. I could have simply applied a nice 4 point moving average, but I wanted to go 'cheaper'. I figured if I took 3/4 of the current value and added 1/4 of the next value to come in, I'd...
