Please, how do I get sign for definite integral (from x1 to x2)?
Many thanks!!!
Hint: Go to the file menu Insert → Object → Formula. The view will change slightly, and you should have a pop-up window with different operators. Play with that window, clicking on different buttons to see what happens and find exactly what you need.
However, to answer the question as asked: I believe you’re looking for the from {}
and to {}
construct.
Go to Insert → Object → Formula.
In the bottom horizontal window, type
int from { -infinity } to { infinity } left ( { x^2 } cdot y^{ -2 } right ) {dx}
That should produce something like .
