a) Create a secante function in a secante.m file on Matlab which uses the secante method for solution of a system of non linear equation. The function stops after a number of iterations Nmax or when the absolute value of the fucntion is smaller than the tolorance .

b)apply this function to the function

with Nmax=30, and = 0.5E-6

fi() = x2 - 5cos(2/3) f2(x) = tan(1/2) - r f3(2) = 50.rlnz 3.0
