A vector space over a field F which also has an associative product defined on the vectors is called an associative F-algebra. Another example of an associative F-algebra: the real vector space, R[x] of real polynomials in an indeterminate x. Exercise 32. For the real vector space, R[x] define linear transformations L and D via L₂(f) = xf D(f) = = dx Show that DL-LD = I, where I is the identity map. Hint: It suffices to show that the claimed identity holds for a basis of R[x].
