"Interpretation of the output above is not obvious (it is easier to understand the output from more complicated alternating forms, as in the next section), but for the moment observe that dx3 is indeed an alternating form, mapping Rn to R with dxi(x1,x2,…,xn)=xi. Thus, for example:"

it should say dx3(x1,...,xn)=x3.
