1. METHODS TO CALCULATE ROOTS OF EQUATIONS DUBAN CASTRO FLOREZ COD:2073091 NUMERIC METHODS IN ENGINEERING 1

3. Those are made derived until the n order.

4. It is replace those derived in the function (being replaced the xi value).

6. The answer is given as Pn(xi+1)=Pn(x). to Remember: n=#derivatives.

7. To calculate the true error2

9. 2.FALSE POSITION The same procedure is continued that the bisection method, to exception of the change in the form of finding xr. 4

11. The xi value is determined knowing the graph of the function (Mathematics of Microsoft or Excel).

12. When it is xi with g(xi), g(xi)=xi+1, that is to say it will be the value to evaluate.

13. If the function doesn't converge the method of clearances of x it is used, the times that it is necessary until the approximate value of g(x) it is similar to that of the f(x root).

14. The first one is evaluated derived in the point to evaluate, if it is gives smaller than 1, it converges, if it is gives bigger it diverges.5

16. To choose an initial value.

17. To find by means of it formulates it of Newton-Raphson.

18. To calculate% Ea.

19. If% Ea =% is then the result of the root it is reported, otherwise to make that the one calculated is the new one and to return to the step 3.

20. The interval is determined to study for half graphic, approaching a value xi to the root, and finding the tangent in that point.

21. This value xi is replaced in f(xi) and in f'(x), it stops then to use the it formulates of up. 6

23. To remember that xi>xi-1

24. When he/she is xi+1, now that it will be my xi and xi-1 it will be the xi that had previously.

25. The necessary xi is calculated until the value is approximate to the real value of the root of the function given.7
