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

If n in N, then find the value of i^(n)+i^(n+1)+i^(n+2)+i^(n+3)

If z=(1-i)^(6)+(1-i) , then find the modulus of z (i.e., |z|) and multiplicative inverse of z (i.e., z^(-1) ).

If ((1+i)/(1-i))^(2) - ((1-i)/(1+i))^(2) = x + iy then find (x,y).

1) Find the value of i^(i)

If sum_(i=1)^(7) i^(2)x_(i) = 1 and sum_(i=1)^(7)(i+1)^(2) x_(i) = 12 and sum_(i=1)^(7)(i+2)^(2)x_(i) = 123 then find the value of sum_(i=1)^(7)(i+3)^(2)x_(i)"____"
