# Halving the Interval Method with Relative Accuracy

Find the smallest positive root of $x^3 – 2x + 1 = 0$ with relative accuracy of $0.5 \%$ by finding good starting value from its graph. According to the graph above, there are three roots, one negative and two positive. Let’s give $f(x) = x^3-2x+1$, then \( f(1) […]
