I like to do:
Plot[Integrate[x^2,x], {x,-3,3}]
and expect a graph of (x^3)/3, but always get various Errors like
Integrate::ilim: "Invalid integration variable or limit(s) in -2.9998774285714287"
It looks like Integrate gets invokved with a concrete value of x. What i
think i need is to get Integrate evaluated first, the result should then be used to do the Plot. But how do i say this to Mathematica? I played with things like Evaluate, Funtion, Apply but was unable to come to a solution.
Thank you for any help in advance,
Thomas
