Question

(D) First,simplify the base expressions: $\frac{1-i}{1+i} = \frac{(1-i)(1-i)}{(1+i)(1-i)} = \frac{1-2i+i^2}{1-i^2} = \frac{1-2i-1}{1+1} = \frac{-2i}{2

(D) First,simplify the base expressions: $\frac{1-i}{1+i} = \frac{(1-i)(1-i)}{(1+i)(1-i)} = \frac{1-2i+i^2}{1-i^2} = \frac{1-2i-1}{1+1} = \frac{-2i}{2} = -i$ $\frac{1+i}{1-i} = \frac{(1+i)(1+i)}{(1-i)(1+i)} = \frac{1+2i+i^2}{1-i^2} = \frac{1+2i-1}{1+1} = \frac{2i}{2} = i$ Now substitute these into the expression: $(-i)^{2022} + (i)^{2021}$ $= (i)^{2022} + (i)^{2021}$ $= (i^{4})^{505} \cdot i^2 + (i^{4})^{505} \cdot i^1$ $= (1)^{505} \cdot (-1) + (1)^{505} \cdot i$ $= -1 + i$
