For these matrices: S=[u,v,-v,u] T=[x,y,-y,x] NOTE: these matrices are 2x2 matrices, the first two on the top row and the last two on the bottom row. (sorry I can't express them properly here). a) Find the determinants of S, T and ST b) Use ordinary algebra to verify that det(S)det(T)=det(ST) c) Express (7^2 + 2^2)(4^2 + 1^2) as a sum of squares of two integers.
