An #Exact #Formula for the #Primes: #Willans’ Formula - YouTube

I didn’t know this formula existed. It was published in 1964 but if you look at it carefully, it’s not a formula as such, it’s actually an #algorithm coded into some nifty #maths. It gets excruciatingly slow for even modest values on n, when n represents the nth prime. I’ve written it as a #maxima code below.
