Hi dear participants,

as a newbie I’ve a question with my notebook:

From the second differentiall (In[3] statement) equation I’d like to plot the solution of it into a graph (In[10] statement). For some reason this doesn’t work. If I extract the solution and enter it as Out[11], then the plot works fine and it yields my result (Out[12] statement). What went wrong?

Your help is greatly appreciated!
Best Regards,
Ralf

Hi Ralf,

check the plot range. In one case you plot from 0 to 100 and in the other from -255 to +255.
