    Generalized Mediant. New root approximating methods

    Allow me to introduce a very simple arithmetical operation: The Arithmonic Mean, which surprisingly and from the evidences at hand, has not been used in mathematics since ancient times up to now. I use the word 'Surprisingly', because it is a generalization of the 'Mediant' operation which is...

    Newtons Third Law

    in each illustrated case, the contact between the blocks and the surfaces are rough (except where indicated) The blocks are at rest and the strings are taut. Find the tension in the string and the frictional force exerted by each surface on the block with which it is in contact. I need help with...

    Newton's Method

    Hi, I can understand the application of Newtons method, (I think) - however doesn't the equation call for the differentiation of f(x) ie the f'(x of k)? I have read through the other posts in relation to this method however remain confused. We have not done derivatives as yet. My equation is...

    Newton's Law of Cooling Problem

    At 1 p.m. a thermometer reading 80F is taken outside where the temperature is constant. At 1:05 p.pm. the thermometer reads 35F more than the surrounding temperature. Forty minutes after being taken outside the thermometer reading differs fromt he outside temperature by 15F. Determine the...

    Linear Speed - Torque

    Suppose the force Ft in the cord hanging from the wheel is given by the relation Ft = 3t - 0.2t^2 (newtons) where t is in seconds. If the wheel starts from rest, what is the linear speed of a point on its rim 8 s later? The Ft force is perpendicular to the wheel's (4 kg) radius = 33 cm. The...

    Newton cotes formula problem

    Hi everyone, Help me to solve this problem... (Please refer attachment for the problem.) By the method of undetermined coefficients i found a=c=1/6 and b=2/3 and alpha=gamma=2/3 and beta=-1/3. Also that both are exact for polynomials of degree<=3. But I cannot figure out which one is better...

    Newton Raphson Method

    Can someone check this is correct? Using the Newton Raphson method with X0=2 to find the root of the equation: x^3-x-1=0 (correct to 4.d.p) My answer is: f'(x)= 3x^2-1 xn+1= 2-x^3-x-1/3x^2-1 xn+1= 2-2^3-2-1/3(2^2)-1 x1= 17/11 x2= 17/11-(17/11^3)-17/11-1/3x(17/11^2)-1 = 1.3596

    Newton's Method Problem

    PROBLEM: Apply Newton’s Method to approximate the x-value of the indicated point of intersection of the two graphs. Express your answer so that it is accurate to as many decimal places as your Sharp EL-531 calculator will give you. Clearly identify your starting value and list your sequence of...

    Newton's method, how do I know there is more than 1 solution?

    I have a question. How is one supposed to know here that there are two answers in this problem? I started with some value (it was 2) and got one correct answers. And if I am solving this purely manually, then there's no convenient way to quickly check it (by graphing), as I understand?

    Newton's Method and Order of Convergence - Numerical Analysis

    Consider the function f(x) = (x^4) - x - 3 Clearly f(x) has a zero between 1 and 2 (a) If Newton's Method with p_0 = 1 is used to approximate the zero of f(x), then identify p_1 and p_2 (b) If Secant Method starting with p_0 = 1 and p_1 = 2 is used on f(x), then identify p_2. (c) Can the...

    newton's second law of motion

    Hi can you please help me? I don't know how to do this question. A sports car of mass 700kg increases its speed from 90km/h to 100km/h during a 5-second interval. The average combined forces of air resistance and road friction, D, at that speed is 200N. Determine the vector for the net force...

    Newton's Method

    There is a chapter in my single variable calculus textbook by the name Newton's Method. I decided to skip this chapter in my self-study of calculus because it made no sense to me. Can someone explain in simple words what is Newton's Method? What is this topic good for? Can you answer the...

    Newton's Method

    My textbook does a terrible job explaining Newton's Method. Can someone explain, in laymen terms, how to apply this method? I guess the best way is using a question.
