Free math tutorial and lessons. Complex numbers The equation x2 + 1 = 0 has no solutions, because for any real number xthe square x 2is nonnegative, and so x + 1 can never be less than 1. Trigonometric form of the complex numbers. If z is real, i.e., b = 0 then z = conjugate of z. Conversely, if z = conjugate of z. Show that zi ⊥ z for all complex z. Section 8.3 Polar Form of Complex Numbers . To divide two complex numbers, you divide the moduli and subtract the arguments. i.e., if a + ib = a − ib then b = − b ⇒ 2b = 0 ⇒ b = 0 (2 ≠ 0 in the real number system).
