Question

Use Euler's method with step size 0.2 to estimate y(1), where y(x) is the solution of the initial-value problem given below. (Round your answer to four decimal places.)
y' = 1 − xy
y(0) = 0

I don't even know how to start!

Answer 1

you might start by reading up on Euler's method. google can help. There's even a youtube video illustrating the method.

There's a good discussion with examples here:
