When solving a Differential Equation y’=y*(5-y) , y(0)=9 numerically using the Euler Method given stepsize of 0.1 use the Differential Equations made Easy app at www.tinspireapps.com and select Euler Method in the Menu as shown below :
Now you just enter the Differential Equation in the top box and the starting point and the step size in the bottom box as shown below:
The bottom box now shows the step by step solution of the Euler Method. Works correctly for any given Differential Equation.
Alternative to the Euler Method you may also the built-in Runga Kutta RK4 method.
