Let `A=((cosalpha,-sinalpha),(sinalpha,cosalpha)),(alpha in RR)` such that `A^(32)=((0,-1),(1,0))`. Then a value of `alpha` is:

Let A=({:(cosalpha,-,sinalpha),(sinalpha,,cosalpha):}),(alphaepsilonR) such that A^(32)=({:(0,-1),(1,0):}) . Then a value of alpha is:

If A=[(cas alpha, sinalpha),(-sinalpha,cosalpha)], AA'=

If A_(alpha)=[(cosalpha,-sinalpha),(sinalpha,cosalpha)] , then

If A=[(cos alpha,sinalpha),(-sinalpha,cosalpha)] , verify that A'A=I_2

Let A_(alpha)=[(cosalpha, -sinalpha,0),(sinalpha, cosalpha, 0),(0,0,1)] , then :

Let A_(alpha)=[(cosalpha, -sinalpha,0),(sinalpha, cosalpha, 0),(0,0,1)] , then :

If A=[(cosalpha,-sinalpha,0),(sinalpha,cosalpha,0),(0,0,1)] then ("Adj A")^(-1) =

If A=[{:(cosalpha,sinalpha),(-sinalpha,cosalpha):}] , then find the value of A'A

If A=[[cosalpha,sinalpha],[-sinalpha,cosalpha]] is such that A^T=A^(-1) , find alpha

If A=[[cosalpha, sinalpha], [-sinalpha, cosalpha]] , then A^(10)=
