(a) Implement the Secant method in 1D and to solve for the zeros the function, f(t) = 5 sin(1) - 1 You can verify your zeros by using MATLAB's builtin function fzero. (b) Implement a 2D Newton's method to solve the system of equations f1(11, 12) = 11 - Cos(21 +22) = 0 f2(21, 12) = 12 sin(x1 + 12) = 0 You can verify your solution scheme by using MATLAB's builtin function fsolve
