Algorithm :
- Start
- Read x, e, n, d
*x is the initial guess
e is the absolute error i.e the desired degree of accuracy
n is for operating loop
d is for checking slope* - Do for i =1 to n in step of 2
- f = f(x)
- f1 = f'(x)
- If ( [f1] < d), then display too small slope and goto
11.
*[ ] is used as modulus sign* - x1 = x – f/f1
- If ( [(x1 – x)/x1] < e ), the display the root as x1 and
goto 11.
*[ ] is used as modulus sign* - x = x1 and end loop
- Display method does not converge due to oscillation.
- Stop
The above algorithm can be applicable for newton raphson method in any degree of polynomial in any high level programming language such as Visual Basic

Calculus Suppose you want to find zeros of the function f(x)102212 and plan to use the Newton-Raphson scheme. (a) Write down the Newton-Raphson algorithm for this. That is, write down explicitly a formula for computing your (n+1)st guess Tn+1 given your nth guess rn for a root. In other words, deter- mine the recurrence relation resulting from using this particular function f. (b) Modifying Algorithm 2.2 as required, find the values through x7 if you choose an...

3. Newton-Raphson algorithm Solve the following problem (Problem 6.30 of the Edition textbook 6 or Problem 6.17 of the textbook Edition 7): You are designing a spherical tank to hold water for a small village in a developing country. The volume of liquid it can hold can be computed as: where V=volume (m3, h-depth of water in tank (m), and R the tank radius (m). If R-3m, what depth must the...

Newton invented the Newton-Raphson method for solving an equation. We are going to ask you to write some code to solve equations. To solve an equation of the form x2-3x + 2-0 we start from an initial guess at the solution: say x,-4.5 Each time we have the i'h guess x, we update it as For our equation,f(x) = x2-3x + 2 andf,(x) = 2x-3. Thus, our update equation is x2 - 3x, 2 2x, - 3 We stop whenever...

8 The Newton-Raphson method. This is a technique which was developed independently approximately 300 years ago by two Isaac Newton and Joseph Raphson. This is an iterative (repetitive) technique which produces successively better approximations for the roots (or zeros) of a real function. Using this technique, if we cannot solve an equation, we can find a very accurate approximation to its roots. Say we cannot solve some equation f(x)- 0. We can investigate its roots by drawing the graph of...
