Where x is in radians

a. Show that f(x) = 0 has a solution, α, in the interval 0.4 < x < 0.5.

b. Taking 0.4 as a first approximation to α, apply the Newton–Raphson process once to f(x) to obtain a second approximation to α. Give your answer to 3 decimal places.

c. Show that x = −1.190 is a different solution, β, of f(x) = 0 correct to 3 decimal places.
