I'm trying to evaluate the limit :::::
Limit[(sqrt[t^2 + 9] - 3)/(t^2), t -> 0]
When i click "evaluate cell" Mathematica outputs :::::
\!\(\*UnderscriptBox[\(\[Limit]\), \(t \[Rule] 0\)]\) (-3 +
sqrt[9 + t^2])/t^2
which is the same thing as what I typed in only in a slightly different order (essentially the same thing i typed in) what am i doing wrong ?
