For a linear transformation

T:R^(2)->R^(2)

, we have:\

T(e_(1))=[[-1],[1]]

and

T(e_(2))=[[-3],[5]]

.\ For another linear transformation

S:R^(2)->R^(2)

, we have:\

S(e_(1))=[[1],[-2]]

and

S(e_(2))=[[3],[-1]]

.\ Then

(S@T)[[-2],[-3]]=[[, /# ],[, /# ],[,]]

For a linear transformation T:R2R2, we ha T(e1)=[11] and T(e2)=[35]. For another linear transformation S:R2R2, S(e1)=[12] and S(e2)=[31]. Then (ST)[23]=[ For a linear transformation T:R2R2, we ha T(e1)=[11] and T(e2)=[35]. For another linear transformation S:R2R2, S(e1)=[12] and S(e2)=[31]. Then (ST)[23]=[
