Need help with Euler method

Hi

I need to compared a Euler method equation with 2 different h values. I've the valves done in excel but cant compare these because the columns dont match up.

The formula is: x_1=x_0+h(αte^(-0.3t)+βx)

I worked it out in excel as: x_n=x_(n-1)+(t_n×(αt_(n-1) e^(-0.3t_(n-1) )+βx_(n-1) ))

Any help is greatly appreciated.

Save arrays t1 and x1 for h1 as well as t2 and x2 for h2.

Then plot x1 vs. t1 and x2 vs. t2.

Best wishes

Torsten.
