Complex Numbers

Allow us to solve equations with a negative root NB: these are complex conjugates usually notated as z and z

Operating on Complex Numbers in Rectangular Form (Cartesian form) Multiplication 6x(3+5i) Addition & Subtraction (3+2i) + (6-i) (2-6i) – (8-4i) Division (3-2i)÷(-7+3i) 30.2 p.278 #2-4 30.3 p.280 even # 30.4 even # 30.6 p.282 #4-8

The Modulus i x 4-2i 4 -2 The modulus of a complex number represents its distance from the origin on an Argand diagram. If a complex number is, then its modulus Example: Evaluate. Example: Evaluate if.
