If `((1 + i) / (1 - i))^3 - ((1-i) / (1 + i))^3` = x + iy then find x and y.

If frac{(1+i)^3}{(1-i)^3}-frac{(1-i)^3}{(1+i)^3} = x+iy , then

Simplify: (1 / i) + (1 / i^2) + (1 / i^3) + (1 / i^4)

If (frac{1+i}{1-i}^3) - (frac{1-i}{1+i}^3) = x+iy, then find (x,y)

If a and b are real and ( i^4 + 3i) a + (i -1) b + 5 i^3 = 0, find a and b

Select and write the correct answer from the given alternatives in each of the following: If x (1 + 3i) + y (2 - i) - 5 + i^3 = 0, then the value of x + y is

If frac{(1+i)^2}{2-i} = x+iy, then find the value of x and y

Simplify: [1 / (1 - 2i) + 3 / (1 + i)] [(3 + 4i) / (2 - 4i)]

Let z =1 + i then x = ? y = ?
