Definition 6.1.2: Inverse of a Complex Number. Let z = a + bi be a complex number. Then the multiplicative inverse of z, written z − 1 exists if and only if a2 + b2 ≠ 0 and is given by. z − 1 = 1 a + bi = 1 a + bi × a − bi a − bi = a − bi a2 + b2 = a a2 + b2 − i b a2 + b2. Note that we may write z − 1 as 1 z.

A proof is a sequence of statements. These statements come in two forms: givens and deductions. The following are the most important types of "givens.''. The P P s are the hypotheses of the theorem. We can assume that the hypotheses are true, because if one of the Pi P i is false, then the implication is true. best weapon for queen slime Then P(n) is true for all natural numbers n. For example, we can prove by induction that all positive integers of the form 2n − 1 are odd. Let P(n) represent " 2n − 1 is odd": (i) For n = 1, 2n − 1 = 2 (1) − 1 = 1, and 1 is odd, since it leaves a remainder of 1 when divided by 2.
