My code is: Plot[D[Integrate[E^(t*(-x^2)),{x,t+2,t^2}],t],{t,-2,3}]
.
The errors/warnings are:
General::ivar: "-1.9999 is not a valid variable."
General::ivar: "-1.89786 is not a valid variable."
General::ivar: "-1.79582 is not a valid variable."
General::stop: "Further output of \!\(\*
StyleBox[
RowBox[{\"General\", \"::\", \"ivar\"}], \"MessageName\"]\) will be suppressed during this calculation. "
The graph turns out empty in the end.
What did I do wrong this time?
Evaluated->True

you will see that has theHoldAll
attribute, hence the expression will remain unevaluated. $\endgroup$ – Spawn1701D Apr 28 '13 at 18:56Plot[Evaluate@D[Integrate[E^(t*(-x^2)),{x,t+2,t^2}],t],{t,-2,3}]
. I'm sure this is a duplicate question, but too lazy to look now:) $\endgroup$ – Ajasja Apr 28 '13 at 18:56
