1- Compute j^j and express the result in cartesian form.
2- Compute (1-j*sqrt(3))^12 and express the result in Cartesian form.
3- Compute 7e^(j*4pi/7)+5e^(-j*5*pi/7) and express the results in both Cartesian form and polar form.
4- Draw phasor diagrams and express your results in both Cartesian and polar form for the following problems:
(A): e^(jpi/4)+e^(j3pi/4)
(B): e^(jpi/3) * e^(jpi/2)+e^jpi
