Hallar los valores aproximados de la solucion del problema dado con valorinicial, en t = t0 + 0.1, t0 + 0.2, t0 + 0.3 y t0 + 0.4:

a) Aplicar el metodo de Euler con h = 0.1

b) Aplicar el metodo de Euler con h = 0.05

c) Aplicar el metodo de Euler con h = 0.025

1. y = ex2, x(0) = 1

a) Aplicando el metodo de Euler: yn+1 = yn + hf(tn, yn) con h = 0.1Sea t1 = 1 + 0.1Para t1 = 1.1y1 = 3 + (0.1)f(1.1 , 3)y1 = 3 + (0.1)(2.0248)y1 = 3.2024

Para t2 = 1.2y2 = 3.2024 + (0.1)f(1.2 , 3.2024)y2 = 3.2024 + (0.1)(2.0982)y2 = 3.4122

Para t3 = 1.3y3 = 3.4122 + (0.1)f(1.3 , 3.4122)y3 = 3.4122 + (0.1)(2.1707)y3 = 3.6292

Para t4 = 1.4y4 = 3.6292 + (0.1)f(1.2 , 3.2024)y4 = 3.6292 + (0.1)(2.0982)y4 = 3.4122

b) Aplicando el metodo de Euler: yn+1 = yn + hf(tn, yn) con h = 0.05

Para t1 = 1.1y1 = 3 + (0.05)f(1.1 , 3)y1 = 3 + (0.05)(2.0248)y1 = 3.1012

Para t2 = 1.15y2 = 3.1012 + (0.05)f(1.15 , 3.1012)

1

y2 = 3.1012 + (0.05)(2.0618)y2 = 3.2042

Para t3 = 1.2y3 = 3.2042 + (0.05)f(1.2 , 3.2042)y3 = 3.2042 + (0.05)(2.0986)y3 = 3.3091

Para t4 = 1.25y4 = 3.3091 + (0.05)f(1.25 , 3.3091)y4 = 3.3091 + (0.05)(2.1352)y4 = 3.4158

Para t5 = 1.3y5 = 3.4158 + (0.05)f(1.3 , 3.4158)y5 = 3.4158 + (0.05)(2.1716)y5 = 3.5243

Para t6 = 1.35y6 = 3.5243 + (0.05)f(1.35 , 3.5243)y6 = 3.5243 + (0.05)(2.2077)y6 = 3.6346

Para t7 = 1.4y7 = 3.6346 + (0.05)f(1.4 , 3.6346)y7 = 3.6346 + (0.05)(2.2438)y7 = 3.7467

Para t8 = 1.45y8 = 3 + (0.05)f(1.45 , 3.7467)y8 = 3 + (0.05)(2.2796)y8 = 3.860

c) De manera similar se obtienen los resultados de h = 0.025 y se muestranen la siguiente tabla:
