Simplification for entering the initial values

A friendly hello to all,

In the attached file from MC14 there are two solution blocks at the end for solving differential equations. So far I had to enter the same initial values in each solution block. Can these initial values be entered only once somewhere before for both solution blocks?

Kind regards, Alfred Flasshaar

How about defining variables with the initial values in front of the first solve block

and using these variables as initial values

Of course you don't need to define the variables uses a vector and you may also use a global definition

so you would be able to set the values anywhere in the sheet, not necessarily in front of the first solve block.

 

But I wonder what the second solve block would be good for? Its the very same as the first one and of course it would yield the very same results. So you could delete it without harm and the sheet would still work OK.
