Π is an Irrational Number (True/False). - Mathematics | Shaalaa.com

Tim Ricchuiti on Instagram: "Pi won’t start repeating after a trillion digits. And it’s not because we checked the digits. We know π is irrational from a proof going back to Lambert in the 1700s. His result shows that if tan(x) is rational (and x ≠ 0), then x must be irrational. But tan(π/4) = 1, and 1 is rational. So π/4 is irrational → π is irrational. #pi #irrationalnumbers #mathreels #mathproofs"
