Is there a differnet between ^[a-zA-Z] or [^a-zA-Z]?

When I check in C#,

Regex.IsMatch("t", "^[a-zA-Z]")  // Return true (I think it's correct)

Regex.IsMatch("t", "[^a-zA-Z]")  // Return false

There are alot of web site using [^a-zA-Z] for alphabet. I'm not really sure which one is correct answer.

Could someone please shed the light?
