from: [tex]f\otimes g: V_1\otimes W_1\rightarrow V_2\otimes W_2[/tex]

where f and g are linear transformations f:V1->V2, g:W1->W2

that satisfies: [tex](f\otimes g)(u\otimes v)=f(u)\otimes g(v)[/tex]

well I think that what I need to show is only that

it's linear by first componenet and second componenet which I did.

well if that's it for linear (including multplication by a scalar), then now I need to show uniqueness, well I guess this depends on f and g is it not?

well it's unique by our choice of f and g, with other functions we would have a different linear transformation.

What do I miss here?

thanks in advance.
