((1+i)/(1-i))^(2)

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

The modulus and amplitude of (1 + 2i)/(1-(1-i)^(2)) are

Consider the complex number z=(2+i)/((1+i)(1-2i)) (i) Express z in the form a+ib .

Given i=sqrt(-1), then the value of the sum (1)/(1+i)+(1)/(1-i)+(1)/(-1+i)+(1)/(-1-i)+(2)/(1+i)+(2)/(1-i)+(2)/(-1+i)+(2)/(-1-)

(1+2i)/(1-(1-i)^2)

Reduce to the form A + IB ((1-i)^2-(1+i)^2)/((1-i)^3+(1+i)^3)

" If "z=((1+i)(1+2i)(1+3i))/((1-i)(2-i)(3-i))" then the principal argument of "z"
