Question
Given the function : f(x) = x³ + 5x² + 7x-20; solve using Secant Method with initial values of (1.000, 2.000)
1st iteration
X0 = 1.000
X1 2.000
xnew = 1.241
2nd iteration
X0 = 2.000
X1 2.000
xnew 1.296
3rd iteration
X0 = 1.241
X1 = 1.296
xnew= 1.310
4th iteration
X0 = 1.296
X1 = 1.310
xnew= 1.310
5th iteration
X0 = -0.001
X1 = -0.001
xnew= 1.310
f(x0) = -7.000
f(x1) = 22.000
f(xnew) = -1.701
f(x0) = 22.000
f(x1) = -1.701
f(xnew) = -0.353
f(x0) = -1.701
f(x1) = -0.353
f(xnew) -0.001
=
f(x0) = -0.001
f(x1) = -0.001
f(xnew) = -0.001
f(x0) = 1.310
f(x1) = -0.001
f(xnew) = -0.001
