Is this "legal" what I did? I mean switching to t like this?
I try, but it gives the following error:
This is not a valid image file.
Anyway, I used another service, can u see this one?
And another thing, is it possible that x=0, according to the point they gave?
You beter hope taht whoever has time to help you with this knows LaTeX well
Forgot about this, for those who do have image hosting.
