Question:

Determine the lowest positive root of ƒ(x) = 8 sin(x) e-x – 1:
(a) Graphically.
(b) Using the Newton-Raphson method (three iterations, xi = 0.3).
(c) Using the secant method (three iterations, xi-l = 0.5 and xi = 0.4).
(d) Using the modified secant method (five iterations, xi = 0.3, δ = 0.01).
