Question

Hi,sorry for my bad english;
Let f[x_]=x^2
I want to integrate numerically this function,by Trapezoidal approach on interval[0,10] and my solution is like this
xold=0;h=0.01;xnew=h;sumution=0;While[xnew<10,sumution=sumution+h/2*(f[xold]+f[xnew]);
xold=xnew;xnew=xnew+h];Print[sumution]
This code gives me alist of datas and I want to plot this datas versus x;how can I do this?plz help me
