Choose the Correct Answer in the Following Question If a = `[(Alpha, Beta),(Gamma, -alpha)]` is Such that A2 = I Then - Mathematics
Choose the correct answer in the following questions:
if A = `[(alpha, beta),(gamma, -alpha)]` is such that A2 = I then
(A) 1 + α² + βγ = 0
(B) 1 – α² + βγ = 0
(C) 1 – α² – βγ = 0
(D) 1 + α² – βγ = 0
On comparing the corresponding elements, we have:
