## Solving "Impossible" Differential Equations with Mathematica

(continued from last page...)

At first it seems that the answer we've been given:

is useless. After all, it's not a proper formula! Well, lets extract the important part of the answer, (i.e. shed the braces) by giving the command:

sol1=sol1[[1,1,2]]

(This says take the first row, first column, second part of the original sol1, and put the result back into sol1 as its new value. Get used to this trick—you will be using it frequently from now on.)

Go ahead and flip to Mathematica, and issue the command now. Come back here when you're done.

Welcome back! Moving on...
