Octave

a) Solve the following initial-value problem using one of the analytical techniques we discussed in

class.

y0 = 􀀀2xy + 1; y(0) = 0 (1)

(b) Use Octave to plot the slope elds and the particular solution of equation(1). For the plot use

a window size of xmin = 􀀀1, xmax = 3, ymin = 􀀀1, ymax = 3.

(c) Use Octave to numerically solve (1) using n = 100 and n = 200 points. Create a plot showing the

two numerical solutions and the analytic solution from part(a). For the plot use xmin = 0, xmax = 8.

(d) Type a report using the following outline as a guide:

ˆ I. Introduction and Objectives

ˆ II. Discussion of the Euler's Method

ˆ III. Discussion of Implementation

{ How were the methods implemented?

{ What kind of problems did you encounter while working with the code?

{ How did you overcome these problems?

ˆ IV. Discussion of Results

{ e.g. compare Euler's solution with the analytical solution
