Hi,

Part "a" of my problem says

"Let y = y(x) be the solution to the initial-value problem

y' = x^2 - y/3, y=y(x), y(1)=0

Use Euler's method with n = 3 steps to estimate the value of y(2) show your steps clearly..."

Anyway, I found the values and they are correct, shown below,

x_0 = 1

y_0 = 0

x_1 = 4/3

y_1 = 1/3

x_2 = 5/3

y_2 = 8/9

x_3 = 2

y_3 = 139/81

But my problem is with part b,

<- from the answer key

It' asking me to graph my values with the graph of the actual solution, which isn't given. How am I supposed to figure out what the actual solution looks like?

Thanks
