## It didn't work with Digits:=20: either...

Hey acer,

It didn't work with Digits:=20:

It actually removed the "minus" from the 0, so it only said "0."

And now, even though I deleted "Digits:=20:", it still gives me "0." rather than "-0." from before. How can I change it back?

## It says -1...

Hey Carl, thanks for your help as well!

I wrote the interface command and it gave me -1, so I don't know what could be the problem then.

## Interesting...

I don't know what this custom initialization file could be :/

But it's interesting that you get the right result without any problems!

## The data...

Sorry! I have attached the data now :)

## Data, mu and Digits...

By "read the mean-value,mu" I just mean reading the number of the mu-symbol."

How do I increase Digits? I haven't used that before. Where can I find it in my residualQQplot?

## Thank you !...

Alright, thanks for the help! :)

I edited my original post, where you can download it at the bottom of the post :)

## Thank you! Again!...

Alright, I think I understand it now. I'll try it. Thank you for all your help!

## Thank you!...

Thank you both very much for your answers! I'll try to make it work that way instead of using "linjeelementer" just.

Just a quick question: What does these commands mean and do? Do I have to write all this every time to plot the slope field with a line showing the movement of the line elements in it?

```RHS:=subs(y(t)=y,rhs(ODE));
z1,z2:=solve(RHS=0,y);
plot(RHS,y=z1-100..z2+100);
SOL:=dsolve({ODE,y(0)=z});
plot(eval(rhs(SOL),z=z1),t=0..800); # Constant (roughly)
plot(eval(rhs(SOL),z=z1+0.001),t=0..800);
plots:-animate(plot,[rhs(SOL),t=0..800],z=z1+0.001..z1+10,trace=5);```
