That is a great help. If I could give thimbs up I would! (not enough rep)

One quick question:

From the result, e.g.) [ 8.68 [G=7.183] 31]

How can I extract the maximum amplitude data only? As in the 8.68 bit? I am trying to use:

ggg:=MAX( , , , ,)

fff:=MIN(, , , ,)

max(ggg, abs(fff))

How can I do this, do you know?

Thanks ever so much

`Nevertheless,If we were to say that:_C3 := 0.5;_C4 := 0;b := 0.8;g := 2000000;e := 2.8;In the range of t from 0 to say 10. I am still unable to plot this function for x(t). `
`Any reason as to why this may be?I do the call (after running dsolve and setting all the values for the variables):plot(x(t), t = 0 .. 10)I just get:Warning, unable to evaluate the function to numeric values in the region; see the plotting command's help page to ensure the calling sequence is correctWith an empty graph displayed also.I would be sooo thankful for any help!!`

Ah I see.

How would one determine these?

Cause I use maple to assist with this?
