why the following double integrate can't get the right answer?
In[1]=Integrate[Cos[x], {x, x0, x}, {x, x0, x}]
Out[1]=(x-x0)^2/2

the right answer is:
In[2]=f = Integrate[Cos[x], {x, x0, x}];
Integrate[f, {x, x0, x}]
Out[2]=-Cos[x] + Cos[x0] + (-x + x0) Sin[x0]

why the first method can't get it?
Thanks for help!
