5.3 Complex Numbers and Complex Arithmetic cont.
Addition and subtraction of complex numbers is defined in rectangular form only as follows:
If A = a + jb and B = c + jd then
A + B = (a + c) + j(b + d) and
A - B = (a - c) + j(b - d)
Multiplication and division is defined in polar form as follows:
If A = A/qA and B = B/qB then
and in rectangular form as follows ...
