2012-03-28 17:52:02 +0200	asked a question	Plotting an integral with a variable as a limit I want to plot a function with a variable as a limit, e.g. look at \int_0^x f(y) d y, but this seems to throw an error when Sage can't analytically integrate the function. `x,y=var('x y') f(y)=integrate(x^x,x,1,y) plot(f,2,10)` Returns `Traceback (click to the left of this block for traceback) ... ValueError: free variable: x` Can anybody help with this, please? Many thanks.
