# Determine the lowest positive root of (x) = 8 sin(x) e-x 1: (a) Graphically. (b) Using the Newton-Raphson method

## Question:

(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).
