Prove (x - 1) is greater than ln (x)

#proof #calculus #inequality In this video, we look at how to prove the mathematical statement (x-1) is greater than ln(x) using calculus techniques. In order to prove the statement (x-1) is greater than ln(x), we use calculus first and second derivative to find the minimum stationary point for the function y = x-1-ln(x) This example is part of the Australian NSW Extension 2 HSC Maths topic - Proofs.
