1. Consider the nonlinear equation f(x) = Isin (m.x) - 2x4 + 2 Perform 3 iterations of the Newton-Raphson method using an initial guess a" = -0.5. Perform 3 iterations of the Secant method using an initial guess r(-1) = 0.69 and r(0) = 0.7 At each step, it is only necessary to calculate *). On the last step show the the values for the two error measures ca = (*) - x(k-1) and the absolute residual error ey at each iteration where we define it as es = If(x(*)) . Discuss the error results
