Determine the lowest positive root of:
f(x) = 7sin(x) √1
Graphically using Matlab. Plot from 0 < x < 4. Using the Newton-Raphson method (Solve by hand with three iterations and Xo = 0.3). Using the secant method, solve by hand with three iterations (X1 = 0.5 and Xo = 0.4). Using the modified secant method (Solve by hand with three iterations Xo = 0.3, Δx = 0.01).
