यदि `A^(2)-A+I=0` तब सिद्ध कीजिए की `A^(-1)=1=I-A`

यदि triangleABC में (If इन triangleABC), a = (1)/(sqrt(6)-sqrt(2)), b = (1)/(sqrt(6)+sqrt(2)), C = 60^(@) तो सिद्ध कीजिए कि (Prove that) c = (sqrt(4))/(2) .

यदि (x-1)/(2) ge 2 , तब x in

यदि (x-1)^(3) (x+1) lt 0 तब x in

सिद्ध कीजिए कि 2tan^(-1)sqrt((b)/(a))=cos^(-1)((a-b)/(a+b))

If A={:[(1+i,-i),(i,1+i)]:}," where "i=sqrt(-1)," and "A^(2)-2A+I=0," then ":A^(-1)=

यदि x + (1)/(x) = 2 है तब x ^(2) + (1)/( x ^(2)) = ?

If A=[[i, 0], [0, (i)/(2)]] , then A^(-1)=
