1.- Utilizando el método de la bisección resolver la ecuación no lineal 𝑒−𝑥
− 𝑥 = 0
partiendo del intervalo inicial [0,1] y con un error relativo inferior al 25%
2.- Determinar, utilizando el método de la bisección, partiendo del intervalo inicial [0,1]
y con un error absoluto menor que 0.1, la raíz real de la función 𝑓(𝑥) = 𝑥𝑒𝑥
− 1
3.- Aplicando el método de la bisección a la ecuación 𝑥3
− 3 = 0, localizar la raíz
cúbica de 3 sobre un intervalo de longitud menor o igual a 0.1, partiendo del intervalo
[1,2].
4.- Empezando con el intervalo [2,3], realizar tres iteraciones del método de falsa
posición a la función 𝑓(𝑥) = 4𝑥4
− 9𝑥3
+ 1, para hallar la raíz.
5.- Resolver, con error relativo inferior al 0.05%, la ecuación no lineal
𝑓(𝑥) = 𝑒−𝑥
− 𝑥 = 0, mediante el método de la secante, tomando como valores iniciales
𝑥1 = 0, 𝑥0 = 1, y sabiendo que r = 0.56714329. Trabajar con redondeo a cuatro cifras
decimales
.
6.- Resolver la ecuación 4 cos(𝑥) = 𝑒𝑥
con un error absoluto menor que 10-4
, usando el
método de Newton-Raphson con 𝑥0 = 1.
