please solve those 2 questions thanks

Problem 19 (Newton-Raphson method). Find the third iterate, 13, in the Newton- Raphson algorithm for the equation f(x) = tanr-1=0 over the interval [0,1/2]. Take the initial condition 20 = 1. If the scheme is converging to the root, round your answer to four significant digits. Otherwise choose "iteration sequence locally diverging from root". (a) 0.7852 (b) 0.7848 ) 0.7854 (d) iteration sequence locally diverging from root (e) None of these Problem 20 (Newton-Raphson method). Use the Newton-Raphson method to find the root of f()= e-*(4 1)-2, with initial guess Io = 6. If the method converges determine the root to four decimal places. (a) 0.8817 (b) 0.8857 ) 0.8897 (d) method fails to converge for this initial condition (e) None of these
