Calculate two iterations of newton's method to approximate a zero of the function using the given initial guess. (round your answers to four decimal places.) f(x) = cos x, x1 = 1.6

x₃=1.599997=1.6

Step-by-step explanation:

f(x)=cos x, x₁=1.6

First iteration

At x₁=1.6

f(x₁)=f(1.6)

=cos(1.6)

=-0.0292

f'(x₁)=f'(1.6)

=-sin(1.6)

=-0.9996
