How use Maple12 to solve a differential equation by using Euler's method?
Consider the differential equation $y^{\prime}=y-2$ with initial condition $y\left(0\right)=1$.
a) Use Euler's method with 4 steps of size 0.2 to estimate $y\left(0.8\right)$
I know how to do this ...

Maple plot problem
I'm tryin to make a 3D plot of a differential-equation. I already found:
$$\begin{align*}
&x_1' = f(t) x_4 - x_2\\
&x_2' = -f(t) x_3 + x_1\\
&x_3' = f(t) x_2 + x_4\\
&x_4' = -f(t) x_1 ...

A series solution of the differential equation: $\frac{d^2u(x)}{dx^2}+ u(x)^n = 0.$
Consider the differential equation
$\frac{d^2u(x)}{dx^2}+ u(x)^n = 0.$
Let the solution be
$u(x) = u_0(x) + p u_1(x) + p^2u_2(x) + \cdots +p^m u_m(x).$
Now we are interested in substituting the ...
