Challenge Problems
Push your limits with challenges.
Question 1
Apply the Newton-Raphson method to approximate the root of the equation x^3 - x - 2 = 0 starting from an initial guess of x0 = 1. Show detailed calculations for three iterations.
💡 Hint: Make sure to calculate both f(x) and f'(x) correctly at each iteration.
Question 2
Using the equation sin(x) - x/2 = 0, find the root starting with x0 = 1. Illustrate the iterations clearly until convergence is evident.
💡 Hint: Consider using a calculator for the sin function and be careful with radians.
