Homework Statement
Use Euler's method with h=0.05 to find approximate values for the solution of the initial-value problem y'=2x^2+3y^2-2, y(2)=1 at x=0.1, 0.2, 0.3.
Homework Equations
None.
The Attempt at a Solution
Here's my work:
y'=2x^2+3y^2-2, y(2)=1
f(x, y)=2x^2+3y^2-2, x0=2, y0=1
y(0.1)=y1=y0+f(2, 1)(0.05)=1.45
y(0.2)=y2=y1+f(2.1, 1.45)(0.05)=2.10638
y(0.3)=y3=y2+f(2.3, 2.10638)(0.05)=3.20091
The answers I got are 1.45, 2.10638 and 3.20091. But are my answers right? Please check my answer and correct me if I'm wrong.
