"A method that is easier to understand and does not make use of the sin function is based on the fact that if X ∼ U(0,1) and Y ∼ U(0,1), then P[X2 +Y2 ≤ 1] = π/4 (see <a style=\"text-decoration: none;\" href=\"https://en.wikipedia.org/wiki/Monte_Carlo_method\"> \"Monte Carlo method\" on Wikipedia </a>). The following code uses this approach:\n"
