If `A=[(i,0),(0,-i)],B=[(0,-1),(1,0)],C=[(0,i),(i,0)]` then

If A=[(i,0),(0,-i)],B=[(0,-1),(1,0)] and C=[(0,i),(i,0)] and I is the unit matrix of order 2, then show that (i) A^(2)=B^(2)=C^(2)=-I (ii) AB=-BA=-C .

If A=[(0,-1),(1,0)],B=[(0,i),(i,0)] then

If A[{:(i,0),(0,-i)]B=[{:(0,-1),(1,0)] and C =[{:(0,i),(i,0):}] where i= sqrt(-1) . Then which one of the following is correct ?

|(i,0),(0,i)|=

If A =({:(i,0),(0,-i):}),B=({:(0,-1),(1,0):}),C=({:(0,i),(i,0):}) wher i = sqrt(-1) , then which one of the following is correct ?

If A=[(0,-1),(1,0)]B=[(0,i),(i,0)]C=[(i,0),(0,-i)] then

If A=[{:(0,1),(-1,0)],B=[{:(i,0),(0,-i):}],C=[{:(0,-i),(-i,0):}] , then which one of the following in not correct ?

If A={:[(0,-1),(1,0)]:} and B={:[(0,i),(i,0)]:} , then

If A=[(i,0),(0,-i)] , then A A'=
