Consider the function f(x) = cos x − 3x + 1. Since ƒ (0)ƒ (=) < 0, ƒ (x) has a root in
[o,]. If we use secant method, with x₁ = 0.5 and x₁ = 0.6, to estimate the root of
f(x) = cos x - 3x + 1, what is x, such that x, estimates the root of
f(x) = cos x - 3x + 1
to six significant digits? (Answer must be in 8 decimal places)
