" "If Find the value of "|[a+ib,c+id],[-c+id,a-ib]|

Evaluate: |(a+ib,c+id),(-c+id,a-id)|

Evaluate det [(a+ib, c +id),(-c+id, a-ib)]

Evaluate det[[a+ib,c+id-c+id,a-ib]]

Evaluate: |{:(" "a+ib,c+id),(-c+id,a-ib):}|

Evaluate det[[a+ib,c+idc-id,a-id]]

Find the adjoint and inverse of each of the following matrices : A = [(a+ib, c +id),(-c + id,a - ib)] where a^(2) + b^(2) + c^(2) + d^(2) = 1

Evaluate the following determinants: |(a+ib , - c + id),(c+id, a-ib)|

If a+ib=c+id, then

Evaluate |(a+ib,c+id),(-c+id,a-ib)| where i=sqrt(-1)

If |[a+ib,c+id],[-c+id,a-ib]|**|[alpha-ibeta,gamma-idelta],[-gamma-idelta,alpha+ibeta]|= |[A-iB,C-iD],[-C-iD,A+iB]| write down the values of A,B,C,D , hence show that the producrs of sums , each of four squares , can be expressed as the sum of four squares
