Answer:
The two iterations of f(x) = 1.5598
Step-by-step explanation:
If we apply Newton's iterations method, we get a new guess of a zero of a function, f(x), xₙ₊₁, using a previous guess of, xₙ.
xₙ₊₁ = xₙ - f(xₙ) / f'(xₙ)
Given;
f(xₙ) = cos x, then f'(xₙ) = - sin x
cos x / - sin x = -cot x
substitute in "-cot x" into the equation
xₙ₊₁ = xₙ - (- cot x)
xₙ₊₁ = xₙ + cot x
x₁ = 0.7
first iteration
x₂ = 0.7 + cot (0.7)
x₂ = 0.7 + 1.18724
x₂ = 1.88724
second iteration
x₃ = 1.88724 + cot (1.88724)
x₃ = 1.88724 - 0.32744
x₃ = 1.5598
To four decimal places = 1.5598
Answer:
no
Step-by-step explanation:
1 + 18 = 12 which is wrong
11 + 9 = 20 but the other one was wrong so it doesnt work for both
Answer:
I have a formula for differentiating a questions on differentiation
Step-by-step explanation:
I have not published it yet but can give a brief summary of it will later use it to solve questions here after publishing it
any time you a given a function or a question to differentiate always write it in this form y=am...will explain the rest later after publishing it. it works for all kind of differentiation questions like product or quotient type of questions
The last one because it starts at -2 and is going back 6 places
