Is it possible to plot integral (as function)?

for examlpe
T(x):int(p(xx),xx,0,x)

I changed the function T(x) to matrix with X,Y coordinates, and only the matrix i can plot.

Hello olik,

Yes it is possible, look at the screenshot below.

Hello.
Thank you. That is great.

However I do not understand the form of function p(xx).
In my opinion there should be
_ _ or a function of x __ p(x) := x-2
_ _ or a function of xx _ p(xx):= xx-2
_ _ ... These options do not work.

And the function p(xx) defined with xx and without x:
- works for plot
_ _ _ _[ plot p(x) does the same as plot x-2 ]
- does not work for evaluating
_ _ _ _[ p(2)= ... "x not defined" ]

Please, can you explain me this?

Thanks Olik

I apologize, was my typo... you're right, p(xx)=xx-2 or p(x)=x-2, doesn't matter... place eval() in the bound of the integral to make the plot working...
