[" 1.Expand the following determinants "],[[" (i) "|[a+ib,c+id],[-c+id,a-ib]|]]

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

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

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: |{:(" "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-id)|

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

Write the following in z=a+ib form: z=1/(c+id)

Write the following in z=a+ib form: z=(e+if)/(c+id)

If a+ib=c+id, then
